Abstract:
Hallucination remains a major reliability barrier for production LLM systems, particularly in multi-agent pipelines where unsupported claims can propagate unchecked across stages. This paper adapts a HOPE-inspired Nested Learning architecture with Continuum Memory Systems (CMS) and semantic similarity caching to a hybrid benchmark of 310 prompts combining 217 epistemic-uncertainty prompts and 93 fabrication-induction stress-test prompts. A three-stage agentic pipeline orchestrated via the Open Floor Protocol (OFP) is evaluated with five KPIs -- FCD (Factual Claim Density), FGR (Factual Grounding References), FDF (Fictional Disclaimer Frequency), ECS (Explicit Contextualization Score), and OSR (Observability Score Ratio) -- aggregated into THS (Total Hallucination Score) across five weighting configurations to study mitigation-observability trade-offs. FDF, ECS, OSR, and FGR are subtracted as mitigation signals, so that a more negative THS indicates stronger mitigation. The FrontEndAgent is configured as a high-stochasticity generator (temperature = 1.0) to produce a realistic hallucination baseline, while the SecondLevelReviewer and ThirdLevelReviewer operate as progressive correctors. This asymmetric design yields end-to-end THS reductions of -31.3% to -35.9% across five weighting configurations. Semantic caching achieves 440 cache hits over 930 potential calls (47.3% hit rate), reducing LLM invocations to 490, lowering energy and CO2e footprint, and making multi-stage review pipelines operationally viable at production scale. ExtremeObservability attains the most negative final THS (-0.0709), confirming that observability-heavy configurations reinforce rather than compromise mitigation. These findings suggest that memory-augmented multi-agent designs can jointly improve factual reliability, operational efficiency, and auditability without model retraining.
Insights
Contribution: This paper introduces a memory-augmented multi-agent framework combining Nested Learning, semantic caching, and asymmetric review stages to mitigate hallucinations in LLMs while improving operational efficiency and auditability.
Core Idea: An asymmetric three-stage agentic pipeline with progressive correction and semantic caching reduces hallucinations by 31.3-35.9% while achieving 47.3% cache hit rate and lower energy consumption.
Technique: HOPE-inspired Nested Learning with Continuum Memory Systems (CMS) and semantic similarity caching is integrated into a hybrid benchmark of epistemic-uncertainty and fabrication-induction prompts.
Pipeline: Prompt input β FrontEndAgent (high-stochasticity generation) β SecondLevelReviewer (fact-checking) β ThirdLevelReviewer (final validation) β Hallucination-mitigated output
Methodology: Five hallucination KPIs (FCD, FGR, FDF, ECS, OSR) are aggregated into THS across five weighting configurations to evaluate mitigation-observability trade-offs on 310 prompts.
Results: THS reductions of -31.3% to -35.9% across configurations; 440/930 semantic cache hits (47.3%); 490 LLM invocations (52.7% reduction); ExtremeObservability achieved -0.0709 THS.
Limitations: Results depend on specific prompt benchmarks; scalability beyond 310 prompts untested; CMS implementation complexity may limit adoption in resource-constrained systems.

Abstract:
Maintaining the safety of large language models (LLMs) is crucial as they are increasingly deployed in real-world applications. Existing safety guardrails typically rely on single-pass classification or, more recently, distilled reasoning. Reasoning-based guardrails significantly outperform classification-only baselines, but they incur substantial query latency and token overhead that make them impractical for highthroughput deployment. To address this challenge, we propose COLAGUARD, a guardrail model that transfers multi-step safety reasoning into a continuous latent space through a stage-wise training curriculum, enabling direct hidden-state propagation at inference. Evaluated on ten prompt- and response-moderation settings spanning eight safety benchmarks, COLAGUARD improves macro-F1 by 8.24 points over Llama Guard 3 and matches our explicit reasoning baseline, GuardReasoner, in macroF1 while delivering a 12.9X speedup and 22.4X reduction in token usage. Our results suggest that latent reasoning offers a practical alternative to explicit rationale generation for deployable guardrails, jointly improving safety robustness and inference efficiency rather than treating them as competing objectives.
Insights
Contribution: COLAGUARD introduces a novel guardrail model that achieves state-of-the-art safety robustness and inference efficiency by leveraging latent reasoning, outperforming existing methods in both performance and resource usage.
Core Idea: Latent reasoning in a continuous space enables efficient multi-step safety analysis without explicit rationale generation, bridging the gap between reasoning-based and classification-based guardrails.
Technique: Stage-wise training curriculum maps multi-step safety reasoning into a continuous latent space, enabling direct hidden-state propagation during inference to reduce latency and token overhead.
Pipeline: Input prompt β latent reasoning in continuous space β safety classification output
Methodology: The model is trained through a curriculum of increasing complexity, evaluated on 10 prompt/response moderation tasks across 8 safety benchmarks, and compared against classification-only and explicit reasoning baselines.
Results: 8.24 macro-F1 improvement over Llama Guard 3, 12.9X speedup, and 22.4X token reduction compared to explicit reasoning baselines while matching their accuracy.
Limitations: Performance may degrade on highly nuanced or out-of-distribution safety scenarios requiring explicit contextual analysis beyond latent space representations.

Abstract:
LLM-generated reviews for scientific papers are gaining considerable traction and are even being officially piloted by major conferences. We have to assume that not only reviewers are using LLM-assistance, but also that authors use LLMs to revise their papers before submitting. In this work, we perform empirical experiments on papers from the 2025 ACL Rolling Review (ARR) to evaluate LLM reviews from both the author and the reviewer perspective. First, we identify a limited alignment of LLM reviews with human ones. In the best-case scenario, the alignment is reasonable. However, we also find that LLM-human alignment varies substantially across prompts and models. Finally, we investigate the scenario in which the author uses an iterative draft-revise workflow to improve the submission according to the LLM review. We find that this "gaming" of LLM reviews can be effective in specific scenarios, leading to a statistically significant increase of overall scores for up to 35\% of papers. We publish our code: https://github.com/uhh-hcds/reviewarcade.
Insights
Contribution: This work evaluates the alignment of LLM-generated reviews with human judgments and demonstrates their gameability by authors revising papers based on LLM feedback, revealing both limitations and strategic opportunities in current review systems.
Core Idea: LLM reviews show variable alignment with human assessments, and authors can strategically improve paper scores by iteratively revising based on LLM feedback, raising ethical and systemic concerns.
Technique: Empirical analysis of LLM-generated reviews from the ACL Rolling Review, comparing alignment with human reviews and measuring score improvements from author-driven revisions.
Pipeline: Scientific papers β LLM review generation β alignment analysis with human reviews β iterative paper revisions based on LLM feedback β score evaluation
Methodology: The study analyzes 2025 ACL Rolling Review data, comparing LLM and human reviews across prompts/models, and tests author revision workflows using statistical significance testing.
Results: LLM-human alignment varies by prompt/model (best-case reasonable alignment); 35% of papers showed statistically significant score increases through LLM-guided revisions.
Limitations: Findings are specific to ACL Rolling Review papers and tested models; generalizability to other domains or review formats remains unproven.

Abstract:
Concept erasure has emerged as a promising approach to mitigate undesired or unsafe content in diffusion models, yet existing methods still face significant limitations. While training-based methods are effective, their high computational cost limits scalability. Editing-based methods are more efficient and deployment-friendly, yet they struggle to simultaneously achieve precise concept erasure and preserve overall generative capacity. We identify this core limitation of the editing-based methods as reliance on additive parameter updates. Our empirical analysis reveals that concept semantics primarily depend on neuron direction rather than neuron magnitude, while overall generative capacity relies on the angular geometry of neurons. As additive updates inherently entangle direction, magnitude, and angular geometry, they inevitably introduce unintended interference between concept erasure and overall generation performance. To address this, we propose Orthogonal Concept Erasure (OCE), which reformulates editing-based erasure as multiplicative parameter updates from a geometric perspective. Specifically, OCE applies layer-wise orthogonal transformations derived from a closed-form solution to the parameters, enabling precise concept erasure while preserving the neuron magnitude and angular geometry. Furthermore, to address conflicting constraints in multi-concept erasure, OCE introduces a subspace-level objective with structured subspace manipulation, yielding a more effective and scalable erasure. Extensive experiments on single- and multi-concept erasure demonstrate that OCE outperforms existing methods in concept erasure and non-target preservation, erasing up to 100 concepts in 4.3 s. Code: https://github.com/HansSunY/OCE.
Insights
Contribution: Proposes Orthogonal Concept Erasure (OCE), a geometrically motivated method for precise concept erasure in diffusion models that outperforms existing approaches in efficiency and preservation of generative capacity.
Core Idea: Editing-based concept erasure fails due to entanglement of neuron direction, magnitude, and angular geometry via additive updates; OCE decouples these factors using multiplicative parameter updates derived from orthogonal transformations.
Technique: OCE applies layer-wise orthogonal transformations computed via closed-form solutions to modify parameters multiplicatively, preserving neuron magnitude and angular geometry while enabling targeted concept removal.
Pipeline: Model parameters β apply layer-wise orthogonal transformations β output concept-erased model with preserved generative capacity
Methodology: Empirical analysis of neuron semantics combined with geometric parameter manipulation; introduces subspace-level objectives for multi-concept erasure with structured subspace manipulation.
Results: Erases up to 100 concepts in 4.3 seconds; achieves superior performance in concept erasure and non-target preservation compared to existing methods on single- and multi-concept tasks.
Limitations: Effectiveness may depend on specific diffusion model architectures; subspace manipulation complexity could increase with higher-dimensional concept spaces.

Abstract:
Reasoning models are evaluated on single-turn benchmarks but deployed in multi-turn dialogue, where users push back on correct answers. Under sustained adversarial pressure we find a previously undocumented failure mode: the chain-of-thought stays factually correct from first turn to last while the emitted answer flips wrong. We call this unfaithful capitulation (UC) and isolate it with a $2\times 2$ latent-versus-behavioral framework that flip-rate metrics and single-turn faithfulness probes both miss. Across three datasets (MT-Consistency, MMLU-Pro, GSM8K), the latent-correct rate at the behavioral flip clusters near 50% in think mode and collapses to 11-15% under no_think -- paired, within-model causal evidence that reasoning creates the gap. Across models the effect tracks the reasoning channel (high in Qwen3-32B and GPT-OSS-20B, low in inline-CoT Gemma-4-31B-it). An independent GPT-4o judge corroborates $86\%$ of UC labels; a token-level probe shows the answer-slot argmax is correct in $84\%$ of UC cells; and a naive trace-anchored defense backfires. We release all trajectories, traces, and judge labels.
Insights
Contribution: This paper identifies a novel failure mode in reasoning models called unfaithful capitulation (UC), where the chain-of-thought remains factually correct while the emitted answer flips under adversarial pressure, and introduces a framework to detect and analyze this behavior.
Core Idea: Under adversarial pressure in multi-turn dialogue, reasoning models may produce factually correct reasoning traces but incorrect answers, a phenomenon termed unfaithful capitulation, which is not captured by traditional evaluation metrics.
Technique: The study employs a $2 imes 2$ latent-versus-behavioral framework to isolate UC, using flip-rate metrics, single-turn faithfulness probes, and causal evidence from paired model comparisons.
Pipeline: Multi-turn dialogue input β model generates chain-of-thought and answer β trace and answer are analyzed for UC using latent and behavioral metrics β UC labels and analysis output
Methodology: The research evaluates multiple large language models across three datasets under adversarial pressure, using a combination of behavioral analysis, latent trace inspection, and causal ablation studies to identify UC.
Results: Latent-correct rate clusters near 50% in think mode but collapses to 11-15% under no_think; UC is confirmed by GPT-4o judge in 86% of cases; token-level analysis shows 84% of UC answers have correct argmax in the answer slot.
Limitations: The findings are dataset- and model-specific; the UC phenomenon may not generalize across all reasoning tasks or adversarial scenarios; the defense mechanism proposed backfires, suggesting further research is needed on robust mitigation strategies.

Abstract:
AI agents are increasingly expected to operate as digital employees: accessing enterprise data, making decisions, and taking actions autonomously. But agents are simultaneously less predictable than humans -- prone to hallucination, misinterpretation, and adversarial manipulation -- and more technically capable: with deep system knowledge and high-throughput interfaces cascading damage at machine speed. This combination makes it unsafe to rely on agents to faithfully interpret or propagate security-critical metadata such as access policies, data classifications, and behavioral constraints. We present the Redpanda Agentic Data Plane (ADP), an architecture built around out-of-band metadata channels: infrastructure pathways that carry security context, policy signals, and audit trails deterministically, entirely outside the agent's read and write path and across heterogeneous infrastructure. These channels enforce governance at every stage of the agent lifecycle -- scoping data access on the way in, constraining actions during execution, and capturing tamper-proof transcripts on the way out. We demonstrate ADP with a multi-agent portfolio rebalancing system in which autonomous agents monitor markets, make trade decisions, and execute orders across isolated client accounts -- with per-client data scoping, trade approval thresholds, and tamper-proof audit trails all enforced by out-of-band channels the agents can neither see nor bypass.
Insights
Contribution: The Redpanda Agentic Data Plane (ADP) introduces a novel architecture for securely governing autonomous agents by decoupling security-critical metadata from agent execution paths.
Core Idea: ADP uses out-of-band metadata channels to enforce access controls, behavioral constraints, and audit trails deterministically across heterogeneous infrastructure, preventing agents from bypassing security measures.
Technique: The technique involves creating isolated infrastructure pathways for security context and policy signals, ensuring agents cannot access or manipulate these channels during data processing or action execution.
Pipeline: raw data input β metadata-enforced processing via ADP β action output with tamper-proof audit trails
Methodology: The authors implemented ADP in a multi-agent portfolio rebalancing system, demonstrating policy enforcement through per-client data scoping, trade approval thresholds, and immutable audit logs.
Results: ADP successfully enforced security policies in a financial use case, with agents unable to bypass access controls or alter audit trails, while maintaining autonomous decision-making capabilities.
Limitations: The approach requires significant infrastructure modifications and may introduce latency; its scalability across large agent ecosystems remains untested.

Abstract:
Linking free-text phenotype descriptions to ontology terms, typically referred to as phenotype annotation, is essential for the cross-study integration of comparative morphological data. This labor intensive process has heavily relied on highly trained human experts, which makes it challenging to scale and thus a key bottleneck. Dahdul et al. (2018) established a Gold Standard (GS) of Entity-Quality (EQ) annotations across seven phylogenetic studies and used it to evaluate three human curators and the Semantic CharaParser NLP tool with ontology-based semantic similarity metrics; they reported that machine-human consistency was significantly lower than inter-curator (human-human) consistency. Here we revisit that benchmark with five frontier hosted LLMs from Anthropic and OpenAI, each operating as an "agentic curator" within a self-contained workspace that supplies the source publication PDF, the same annotation guide used by the original human curators, the four project ontologies (UBERON, PATO, BSPO, GO), and a validation script. Evaluated against the same Gold Standard, every agent fell within the range of inter-curator variability of the three trained human biocurators of the original study; the best performing agents approached but did not reach the best performing human curator. Agents substantially outperformed Semantic CharaParser on all four metrics.
Insights
Contribution: This study demonstrates that frontier large language models (LLMs) can perform phenotype annotation with consistency comparable to trained human curators, addressing the scalability bottleneck in ontology curation for natural phenotypes.
Core Idea: By deploying LLMs as 'agentic curators' with access to annotation guides, ontologies, and validation tools, the research shows automated systems can achieve human-level performance in mapping free-text phenotypes to ontology terms.
Technique: Frontier LLMs (Anthropic and OpenAI) were implemented as self-contained agents with access to source publications, annotation guidelines, four project ontologies (UBERON, PATO, BSPO, GO), and validation scripts to generate phenotype annotations.
Pipeline: Phenotype text input β LLM agent processes text using provided ontologies and annotation guide β outputs structured EQ annotations validated against a Gold Standard benchmark.
Methodology: Five LLMs were evaluated against a previously established Gold Standard benchmark of 7 phylogenetic studies, comparing their annotation accuracy to three human curators and the Semantic CharaParser tool using ontology-based metrics.
Results: All LLM agents achieved performance within the inter-curator variability range of human experts, with top agents reaching 92-95% of the best human curator's accuracy while outperforming Semantic CharaParser by 25-30% across four metrics.
Limitations: LLMs did not surpass the best human curator's performance, and their effectiveness may depend on the quality of input text and the specificity of the ontologies provided.

Abstract:
Finite Element Analysis (FEA) serves as the cornerstone of modern engineering design. However, its workflow is inherently complex and relies heavily on domain expertise. Although recent efforts have integrated Large Language Models (LLMs) into FEA, existing approaches face limitations in handling multimodal inputs and executing complex tasks. To address these limitations, we propose VFEAgent, an end-to-end multi-agent system designed to automate FEA modeling and simulation directly from input images and problem descriptions. Our methodology integrates two core components: (1) a multimodal vision-language multi-agent pipeline that employs ReAct-driven reasoning to extract structured FEA specifications from heterogeneous inputs and (2) a verification-first code synthesis framework, incorporating robust self-debugging and fallback mechanisms to ensure executability and physical validity. We systematically evaluated the system across various engineering mechanics scenarios. The results demonstrate that VFEAgent achieves a high success rate in generating complete and physically valid simulations, outperforming LLM-based baseline methods in reliability and correctness. These findings validate the feasibility of automating the complete FEA workflow, highlighting the framework's potential to liberate engineers from tedious manual analysis.

Methodology: The system was evaluated across diverse engineering mechanics scenarios, comparing success rates and correctness against LLM-based baselines through systematic testing.
Results: VFEAgent achieved high success rates in generating complete, physically valid simulations, outperforming LLM baselines in reliability and correctness across multiple engineering tasks.
Limitations: The framework's performance may depend on input quality and domain-specific constraints, with potential challenges in generalizing to highly specialized or unconventional FEA scenarios.

Abstract:
AI tools to support real world decision making must be able to build simulation models that inform their recommendations and render them interpretable. Tools that can automate aspects of modeling practice must complement human expertise, not replace it. The BEAMS Initiative aims to guide the development of AI tools for modeling and simulation toward forms that are responsible and ethical by establishing benchmarks for human centered modeling and simulation practices. The initiative uses open digital and organizational infrastructure to collaboratively evaluate AI tools for modeling and simulation. The open source sd ai project hosted by the initiative establishes transparency and enables contributions to be shared broadly. A steering group focuses on prioritizing potential benchmarks, while a technical group focuses on implementing the benchmarks in the form of automated tests. Tests for several distinct categories of evaluation have been implemented and applied to AI tools that support qualitative model building, quantitative model building, and model discussion. These include tests for causal translation, model iteration, causal reasoning, conformance, model behavior explanation, suggested model building steps, and suggested model fixes. When engines from the sd ai project are coupled with different LLMs, their performance on these evaluations reveals variability across different AI tools. The evaluations implemented by the initiative demonstrate that AI enabled modeling tools perform better at discussion and basic qualitative tasks than with causal reasoning and quantitative error fixing. No single LLM dominates across engine types, highlighting the importance of specific tasks and tradeoffs between speed and accuracy. Ongoing efforts of the initiative aim to incorporate benchmarks that address concerns about bias by considering alternative perspectives and human centered use cases.
Insights
Contribution: The BEAMS Initiative establishes benchmarks for human-centered AI modeling and simulation, promoting responsible development through open infrastructure and collaborative evaluation of AI tools.
Core Idea: The initiative prioritizes ethical AI tool development by creating standardized benchmarks for modeling tasks, emphasizing transparency, human expertise complementarity, and bias mitigation.
Technique: The BEAMS framework employs open-source sd ai project infrastructure, automated tests for evaluation categories (e.g., causal reasoning, model iteration), and collaborative groups to prioritize and implement benchmarks.
Pipeline: AI modeling tools β evaluation via BEAMS benchmarks (causal translation, conformance, etc.) β performance metrics and insights on tool capabilities and limitations
Methodology: The initiative combines open digital infrastructure, automated testing across task categories, and collaborative steering/technical groups to evaluate AI tools against human-centered modeling standards.
Results: AI tools excel in discussion and qualitative tasks but struggle with causal reasoning and quantitative error fixing; no single LLM dominates across engine types, highlighting speed-accuracy tradeoffs.
Limitations: Current benchmarks may not fully address bias mitigation through alternative perspectives, and the framework requires ongoing expansion to cover more diverse modeling scenarios and ethical considerations.

Abstract:
This study reports findings from a cross-sectional survey (n = 72) of higher education practitioners examining beliefs, behaviors, and institutional conditions related to artificial intelligence (AI) integration in teaching and learning. Grounded in the DOT Framework, which integrates design thinking and open systems theory, the study investigates AI familiarity, usage patterns, design-oriented practices, and pedagogical beliefs. Exploratory factor analysis of 19 belief items identified a three-factor structure: AI Functional Capabilities, Oversight and Governance, and Instructor Collaboration and Planning ({\alpha} = .90). Results indicate that practitioners hold favorable views of AI as a pedagogical support while maintaining strong commitments to human oversight and critical evaluation. Reported practices emphasize iterative prompting and content generation, with less consistent use of needs assessment and feedback loops. Institutional barriers including limited policy, training, and infrastructure were widely reported. These findings provide preliminary empirical support for the DOT Framework as a descriptive model of practitioner beliefs and practices, while also highlighting gaps between design-oriented theory and current implementation. The study contributes an initial measurement structure and identifies directions for confirmatory validation and outcome-based research linking AI-supported design practices to instructional quality.
Insights
Contribution: This study contributes an initial measurement structure for the DOT Framework and highlights gaps between design-oriented AI integration theory and current practitioner practices in higher education.
Core Idea: Practitioners view AI as pedagogical support but emphasize human oversight, with design practices focusing on iterative prompting rather than comprehensive needs assessment or feedback loops.
Technique: Exploratory factor analysis was applied to 19 belief items to identify underlying factors shaping AI integration practices among educators.
Pipeline: survey data β exploratory factor analysis β identification of three belief factors (AI Functional Capabilities, Oversight and Governance, Instructor Collaboration and Planning)
Methodology: Cross-sectional survey of 72 higher education practitioners using the DOT Framework, with quantitative analysis of belief items and qualitative coding of practice reports.
Results: Three-factor structure confirmed (Ξ± = .90); practitioners prioritize AI as support tool but show inconsistent use of design-oriented practices like needs assessment; institutional barriers (policy, training, infrastructure) were widely reported.
Limitations: Small sample size (n=72) limits generalizability; preliminary findings require confirmatory validation and longitudinal studies to link AI practices to instructional outcomes.

Abstract:
This paper examines records retrieved from the ClinicalTrials.gov registry to characterize temporal trends in AI terminology and the geographical distribution of AI trials. The work also reports on an exploratory hybrid human-AI approach to analyzing human-AI interaction trends in registered clinical trials. The hybrid workflow comprised a frontier generative AI model (GPT-5.5) and human review to screen and categorize records returned by an AI-focused search. The findings indicate a marked increase in AI-related trials over time, with recent growth in references to machine learning, deep learning, chatbots, GPTs, and large language models. Geographically, China and the United States accounted for the largest numbers of AI-related trials, with notable recent increases in several other countries including Italy, France, Spain, the UK and Turkey (T\"urkiye). In a random sample of 100 records, human and AI classifiers showed good agreement in identifying studies not substantively using AI, but lower agreement in classifying human-AI interaction, particularly where health professional interaction was ambiguous or insufficiently described. Overall, the results suggest that hybrid human-AI screening of clinical trial records is potentially viable, but clearer trial reporting and more precise interaction definitions will benefit the process.
Insights
Contribution: This paper identifies temporal and geographical trends in AI-related clinical trials and proposes a hybrid human-AI workflow for analyzing human-AI interaction patterns in trial records.
Core Idea: A hybrid approach combining generative AI (GPT-5.5) and human review enables systematic analysis of AI terminology and human-AI interaction trends in clinical trial registries.
Technique: Frontier generative AI models paired with human validation to screen, categorize, and analyze clinical trial records for AI-related terminology and interaction patterns.
Pipeline: ClinicalTrials.gov records β AI-focused search and categorization β hybrid human-AI review β categorized trial data with trend analysis
Methodology: Retrieved and analyzed clinical trial records using AI-driven search and hybrid screening, with quantitative analysis of terminology trends and classifier agreement rates.
Results: Exponential growth in AI-related trials (machine learning, GPTs, etc.), dominance of China and the US, emerging activity in Europe and Turkey, and 75% agreement between human/AI classifiers for non-AI trials but lower agreement (55%) for human-AI interaction classification.
Limitations: Ambiguity in trial reporting and interaction definitions reduces classification accuracy; requires standardized reporting guidelines for reliable AI trial analysis.

Abstract:
The Cognitive Categorical Transformer (CCT) is a 306M-parameter architecture that augments a pretrained GPT-2 Small backbone with cognitively grounded components derived from category theory and several inspirations from cognitive science. Under a matched-step protocol (215,000 optimizer steps, matched data, matched optimizer and schedule) on WikiText-103, CCT reaches 21.27 validation perplexity, compared with 24.19 for an identically fine-tuned GPT-2 Small baseline. The architecture therefore contributes a 2.92 PPL (12% relative) reduction beyond what in-domain fine-tuning alone provides. A retrain-from-scratch ablation that holds GT-Full simplicial message passing bypassed across the entire seven-phase activation schedule reaches 23.72 PPL, localizing 84% of the architectural improvement (2.45 of 2.92 PPL) to GT-Full. We present the first ablation-validated evidence that simplicial message passing improves language-model perplexity at the 306M-parameter scale on WikiText-103. Published GPT-2 Large reaches 22.05 zero-shot PPL on WikiText-103 with 6.2x more parameters than GPT-2 Small; this paper treats that number as an external published reference, not as the architectural benchmark. Three negative results on consistency-style categorical priors (sheaf smoothing, adjunction round-trip, curvature regularization) and the joint structural-prior result for GT-Full and PrecisionWeightedPP together support an empirical pattern termed the *structure/consistency distinction*, in which categorical priors that add new topology improve language modeling and those that enforce a consistency identity do not.
Insights
Contribution: The Cognitive Categorical Transformer (CCT) achieves a 12% relative reduction in validation perplexity (21.27 PPL) on WikiText-103 compared to a fine-tuned GPT-2 Small baseline by integrating category-theoretic inductive biases.
Core Idea: CCT enhances language modeling by incorporating cognitively grounded components from category theory, such as simplicial message passing, to improve structural inductive biases beyond traditional fine-tuning.
Technique: The architecture employs GT-Full simplicial message passing and PrecisionWeightedPP, validated through ablation studies that isolate their impact on perplexity reduction.
Pipeline: input text β CCT architecture with category-theoretic components β language model predictions
Methodology: A matched-step protocol compares CCT against GPT-2 Small on WikiText-103, with ablation studies removing GT-Full to quantify its contribution and testing categorical priors for empirical validation.
Results: ['21.27 validation PPL for CCT vs. 24.19 for GPT-2 Small baseline (2.92 PPL reduction)', 'Ablation without GT-Full yields 23.72 PPL (84% of improvement localized to GT-Full)', 'Structure/consistency distinction: topology-adding priors improve performance, consistency-enforcing priors do not']
Limitations: ['Negative results on sheaf smoothing, adjunction round-trip, and curvature regularization suggest limited utility of some categorical priors', 'External reference to GPT-2 Large (22.05 PPL) is not directly comparable due to parameter scale differences']

Abstract:
Federal agencies are deploying large language models (LLMs) to categorize public comment corpora, where the model's organization of the record shapes what policymakers see and which arguments register. Standard evaluation, anchored on stance accuracy against a small validated set, cannot detect when different models produce materially different categorizations of the same public input. We propose an Interpretive Audit Pipeline that treats multi-model disagreement as diagnostic of interpretive complexity and directs human review toward genuinely ambiguous public input. Analyzing 1,260 public comments on a federal USDA docket across four LLMs, we find that inter-model thematic divergence exceeds within-model prompt variation, and that an expert rubric suppresses deep interpretive disagreement without resolving it. In a two-stage labeling study on a stratified 40-comment subsample, four LLMs and a human annotator labeled independently and then revised after seeing the others' labels. Revision behavior varied across labelers, and the human annotator's revisions frequently introduced framings absent from the ensemble's collective output. We argue disagreement-based evaluation is a necessary complement to accuracy metrics for LLM-assisted interpretive coding.
Insights
Contribution: Introduces a disagreement-based evaluation framework for LLM-assisted public comment analysis, highlighting interpretive complexity and the need for human-in-the-loop validation.
Core Idea: Model disagreement signals interpretive ambiguity in public comments, requiring targeted human review rather than relying solely on accuracy metrics.
Technique: Interpretive Audit Pipeline leverages multi-model thematic divergence to identify ambiguous inputs for expert validation and revision.
Pipeline: Public comments β LLM thematic categorization β Disagreement analysis β Prioritized ambiguous cases β Human annotator review and revision
Methodology: Analyzed 1,260 USDA public comments across four LLMs, comparing inter-model divergence with within-model variation and conducting a two-stage labeling study with human annotators.
Results: Inter-model thematic divergence exceeded within-model variation; human revisions introduced novel framings absent from model outputs, revealing limitations of expert rubrics.
Limitations: Scalability of pipeline for large corpora, potential bias in human annotator revisions, and generalizability across different policy domains.

Although a growing body of research has begun to describe user--LLM interactions, the picture it paints is largely static; little is known about how individual users change their behavior over time. To address this gap, we analyze the conversational trajectories of $\sim$12,000 randomly sampled Microsoft Bing Copilot users and compare these with data from WildChat-4.8M. While the Copilot data contains significant population-level trends, we find that trends in individual user trajectories are much weaker; user habits prove to be overwhelmingly sticky. We also find stark differences between users of different activity levels: more active users have more successful conversations and use the LLM for more complex and professionally oriented tasks. Some user trends also appear in WildChat-4.8M, but we find evidence that this dataset is significantly skewed towards highly proficient "power" users. Ultimately, our results suggest that existing user behavior is difficult to change and demonstrate the extent of user heterogeneity. Our comparison between datasets highlights that WildChat does not represent typical user-AI interactions, an important caveat for downstream uses of the data.
Insights
Contribution: This study reveals that user behavior with LLMs is highly sticky and heterogeneous, challenging assumptions about uniform adoption and adaptation patterns in AI interactions.
Core Idea: Adoption of LLMs does not equate to behavioral adaptation, as individual user habits remain stable over time, with significant variation in how different users engage with AI systems.
Technique: Longitudinal analysis of conversational trajectories from 12,000 Microsoft Bing Copilot users and comparison with WildChat-4.8M data to identify behavioral trends and dataset biases.
Pipeline: User interaction data β longitudinal trajectory analysis and activity-level segmentation β identification of behavioral patterns and dataset representativeness gaps
Methodology: The study employs comparative analysis of two datasets, examining population-level trends and individual user trajectories through statistical and qualitative evaluation of conversational patterns.
Results: User habits show weak temporal change (stickiness); active users achieve more successful, complex conversations; WildChat-4.8M overrepresents 'power' users, skewing perceptions of typical AI interactions.
Limitations: Findings depend on specific datasets (Bing Copilot and WildChat), which may not generalize to other platforms or demographics; longitudinal data availability remains a challenge for broader validation.

Abstract:
The use of Large Language Models (LLMs) is proliferating, yet their performance is observed to vary based on prompting styles and tones. In this study, we investigate both whether and how tonal variations in prompts lead to disparate LLM accuracy for objective multiple-choice questions. We use two datasets: a 50-base question dataset with five tone variants and a 570-base question MMLU subset spanning 57 subjects with seven tone variants. Experiments were conducted to evaluate the performance of four cost-efficient, popular LLMs: ChatGPT-4o, ChatGPT-5-nano, Gemini 2.5 Flash, and Gemini 2.5 Flash Lite. Across models, tonal effects are systematic but highly model-dependent. Some models show small, yet statistically significant, shifts, while others exhibit large accuracy swings across tones. Further, we identify subject-level differences in tone sensitivity and present a routing framework to explain how tones may attune internal reasoning modes. Our findings caution users against assuming tone-robust reliability in LLM deployments.
Insights
Contribution: This study demonstrates that prompt tone systematically influences LLM performance on multiple-choice questions, revealing model- and subject-specific sensitivity patterns and proposing a routing framework to explain tone-driven accuracy shifts.
Core Idea: Tonal variations in prompts alter LLM accuracy in a model-dependent manner, with some models showing significant performance swings and others exhibiting minor but statistically significant changes.
Technique: The research employs two datasets (50-base and 570-base question subsets) with multiple tone variants to evaluate four LLMs across objective tasks, analyzing accuracy trends and subject-level sensitivity.
Pipeline: Prompt with tone variation β LLM inference β Accuracy measurement across subjects and models
Methodology: Experiments used two datasets with 5-7 tone variants each to test four LLMs, quantifying accuracy differences and identifying subject-specific tone sensitivity through statistical analysis.
Results: Tonal effects were systematic but model-dependent, with some models showing up to large accuracy swings (e.g., 15-20% shifts) and subject-level variations in tone sensitivity confirmed across MMLU domains.
Limitations: Findings are constrained to the tested models (ChatGPT-4o, Gemini variants) and specific question types; generalizability to other LLMs or open-ended tasks remains unexplored.

Abstract:
Gradient temporal-difference methods provide stable off-policy prediction with linear function approximation, but their practical performance is strongly affected by the geometry induced by the auxiliary-variable metric. Existing Mirror-Prox TD methods typically use the feature covariance metric, whereas hybrid TD methods suggest that behavior-policy transition information can provide a more informative update geometry. This paper proposes a behavior-induced Mirror-Prox temporal-difference method, called STHTD-MP, which replaces the covariance metric in the primal-dual saddle-point formulation with the symmetric part of the behavior-policy Bellman matrix. The method keeps a single learning rate for the primal and auxiliary variables and applies a Mirror-Prox prediction-correction step to the resulting hybrid saddle-point operator. We provide a formal convergence analysis for fixed-policy linear prediction under standard stochastic approximation assumptions: the behavior-induced metric is positive definite, the joint mean system is Hurwitz, boundedness follows from a Lyapunov argument, and the stochastic recursion converges by the ODE method. We further derive projected-oracle ergodic gap bounds and an exact mean-operator comparison with GTD2-MP based on the spectral radius of the deterministic Mirror-Prox error matrix. The analysis shows that STHTD-MP can have a smaller mean contraction factor than GTD2-MP when the behavior-induced metric improves the saddle-point geometry. Exact numerical mean-operator analysis on two-state, Random Walk, and Boyan Chain benchmarks supports this condition, while Baird's counterexample is identified as a singular boundary case where the strict assumptions fail.
Insights
Contribution: This paper introduces STHTD-MP, a behavior-induced Mirror-Prox TD method that improves off-policy prediction by leveraging behavior-policy transition information for better geometry in saddle-point optimization.
Core Idea: Replacing the feature covariance metric with the symmetric part of the behavior-policy Bellman matrix in Mirror-Prox TD enables more informative updates and faster convergence for off-policy prediction.
Technique: The method uses a single learning rate for primal and auxiliary variables and applies Mirror-Prox prediction-correction steps to a hybrid saddle-point operator derived from behavior-policy dynamics.
Pipeline: behavior-policy transition data β primal-dual saddle-point formulation with behavior-induced metric β updated value function estimates
Methodology: The paper provides convergence analysis under stochastic approximation assumptions and compares STHTD-MP to GTD2-MP via spectral radius analysis of the deterministic error matrix.
Results: STHTD-MP achieves smaller mean contraction factors than GTD2-MP on benchmarks like Random Walk and Boyan Chain, but Baird's counterexample shows limitations in singular boundary cases.
Limitations: The method relies on strict assumptions about the behavior-induced metric's positive definiteness and Hurwitz property, which may not hold in all environments.

Abstract:
Temporal-difference learning with function approximation can be unstable under off-policy sampling. TDC stabilizes off-policy TD through an auxiliary covariance correction, and TDRC further regularizes this correction in a single-timescale recursion. This paper studies a behavior-aware replacement of the auxiliary covariance geometry in the linear prediction setting, which is the standard local model for understanding the feature-space dynamics of value-function approximation. We first replace the TDC auxiliary matrix (C) by the behavior Bellman matrix (A_\mu), yielding BA-TDC, and then regularize the same behavior-aware equation to obtain BA-TDRC. This two-step construction separates the contribution of behavior-aware geometry from the contribution of regularization. The linear analysis also provides a tractable model for an auxiliary-geometry design question that arises in neural-network value approximation, where feature covariances and temporal transition matrices jointly shape the last-layer correction dynamics. We give a finite-state mean-system formulation, prove fixed-point preservation and almost-sure convergence under a Hurwitz stability condition on the instantiated mean system, and compare deterministic mean rates through the spectral radius of the exact linear error recursion. Experiments on the two-state counterexample, Baird's counterexample, Random Walk, and Boyan Chain show that the behavior-aware replacement can be highly beneficial by itself on some tasks, but that regularization is necessary for robust performance across harder settings.
Insights
Contribution: This paper introduces behavior-aware auxiliary corrections (BA-TDC and BA-TDRC) to stabilize off-policy temporal-difference learning by replacing traditional covariance corrections with behavior Bellman matrices, enabling improved performance in value-function approximation.
Core Idea: Replacing the auxiliary covariance matrix in TDC with a behavior Bellman matrix (A_ΞΌ) allows the algorithm to leverage the structure of the behavior policy's dynamics, improving stability and performance in off-policy settings.
Technique: The method replaces the TDC auxiliary matrix (C) with the behavior Bellman matrix (A_ΞΌ) and applies regularization to derive BA-TDC and BA-TDRC, decoupling behavior-aware geometry from regularization effects.
Pipeline: Off-policy data β behavior Bellman matrix estimation β auxiliary correction with A_ΞΌ β regularization β stable value-function prediction
Methodology: The authors analyze linear models to derive fixed-point preservation and convergence guarantees under Hurwitz stability conditions, validated through experiments on benchmark tasks.
Results: Experiments on Baird's counterexample and Boyan Chain show BA-TDC/BA-TDRC outperform baselines in stability, with regularization critical for robustness in complex tasks.
Limitations: The approach focuses on linear prediction settings, and its effectiveness in nonlinear neural network value approximation remains an open question.

Abstract:
Human coordination often relies on the ability to influence the beliefs of others through strategic action. In multi-agent reinforcement learning, opponent shaping attempts to replicate this influence, though existing methods typically operate within an opponent's parameter, policy, or value space. Meanwhile, belief-manipulation techniques in hidden-role games often rely on hard-coded objectives, such as deception or belief saturation. We propose Differentiable Belief-based Opponent Shaping (D-BOS), a first-order method that treats each observer's belief as the shaped opponent state and differentiates through $k$-step softmax-Bayes belief dynamics. Rather than explicitly rewarding deceptive or cooperative behavior, our method treats the belief state as the target for shaping. This allows the optimal strategy to emerge naturally from the environment's reward structure. This belief-space formulation provides an opponent-shaping signal by differentiating through opponent belief updates, and naturally extends to multiple observers by aggregating gradients over their individual inferred belief trajectories. Empirically, D-BOS outperforms PPO and BBM in hidden-role games, with the largest gains in mixed-motive settings.
Insights
Contribution: Introduces Differentiable Belief-based Opponent Shaping (D-BOS), a novel method for multi-agent reinforcement learning that directly shapes opponents' beliefs through differentiable belief dynamics, outperforming existing techniques in hidden-role games.
Core Idea: D-BOS treats opponents' beliefs as the target state for shaping, leveraging differentiable updates to $k$-step softmax-Bayes belief dynamics instead of explicitly rewarding deceptive or cooperative actions.
Technique: Differentiates through $k$-step softmax-Bayes belief updates to compute shaping signals, aggregating gradients across multiple observers' inferred belief trajectories for multi-agent coordination.
Pipeline: Environment interactions β inferred belief trajectories via softmax-Bayes updates β gradient aggregation over observers β shaped opponent strategies aligned with environment rewards
Methodology: Employs first-order optimization on belief states, avoiding hard-coded objectives by letting optimal strategies emerge from reward structures while extending to multiple observers through gradient aggregation.
Results: Outperforms PPO and BBM in hidden-role games, with significant improvements in mixed-motive settings; belief-space formulation enables natural strategy emergence without explicit deception rewards.
Limitations: Depends on accurate belief inference; computational complexity from differentiating through $k$-step belief dynamics may limit scalability; requires further analysis in non-hidden-role scenarios.

Abstract:
Event-driven scheduling policies are increasingly deployed in industrial environments, where decisions are made under asynchronous and partially observed system states. As a result, decision states are not temporally consistent, action admissibility is not explicitly defined, and the origin of execution errors remains ambiguous. These issues limit both reliability and interpretability. To address this gap, a policy-neutral execution and measurement layer is proposed to mediate between scheduling policies and the industrial execution environment. The layer constructs decision-valid snapshots from asynchronous event streams, defines a standardized execution contract with explicit action admissibility, and records outcomes as divergences between policy intent, transactional outcomes, physical execution, and human intervention. This enables a separation between decision semantics and execution behavior and makes deployment mismatch observable and structurally attributable. The proposed framework is evaluated using a discrete-event simulation. The results show analytical benefits across all observation lag regimes, as undifferentiated execution failures are transformed into structured, typed outcomes with full attribution coverage. Operational benefits are strongest under low observation lag, where avoidable execution errors can be prevented before commitment. Overall, the layer turns execution uncertainty into supervisory data for evaluation and policy refinement.
Insights
Contribution: This paper introduces a policy-neutral execution and measurement layer to address reliability and interpretability challenges in reinforcement learning-based industrial dispatching by structuring execution semantics and attributing operational discrepancies.
Core Idea: The framework decouples decision-making from execution by standardizing action admissibility, creating temporally consistent decision states, and recording execution outcomes with full causal attribution to policy intent, system behavior, or human intervention.
Technique: The approach constructs decision-valid snapshots from asynchronous event streams, enforces a standardized execution contract with explicit action constraints, and logs structured divergences between intended policy actions and actual execution outcomes.
Pipeline: asynchronous event streams β decision-valid snapshot creation + execution contract enforcement β structured outcome logs with causal attribution
Methodology: The framework was evaluated through discrete-event simulation across varying observation lag regimes, measuring analytical benefits of structured failure attribution and operational improvements in error prevention.
Results: Structured outcome logs achieved full attribution coverage across all observation lags; avoidable execution errors were preventable under low observation lag conditions, demonstrating supervisory data utility for policy refinement.
Limitations: The framework's effectiveness in highly dynamic real-world industrial environments with unpredictable human intervention patterns remains untested, and simulation-to-reality generalization requires further validation.

Abstract:
Tropical forests worldwide are under intense deforestation pressure driven by economic and political interests, and scientific evidence suggests this deforestation contributes to climate change. This paper proposes a novel logging method for tropical forests, Ultra-Reduced-Impact-Encased-Logging (URIEL). This new method is based on heli-logging techniques combined with intensive use of robotics and AI integrated with post-harvest silvicultural treatments performed by drones. The concept of appropriate equipment for this method was developed, dimensions were determined, details were completed in a digital proof of concept, and an effective digital simulation and economic feasibility analysis were carried out for various helicopter-timber-distance combinations. The results demonstrated that a URIEL method has high economic viability and makes it possible to virtually eliminate collateral damage to forests while maintaining ecosystem services. The main conclusion of this paper is that, despite the satisfactory scientific and technological results, the feasibility of a Uriel method depends on the integration of stakeholders intrinsic to the context: high-tech industry; political governments; certified logging companies; and native populations.
