Researchers introduce 'skill coverage,' a test adequacy metric that measures whether AI agent skills are thoroughly exercised during evaluation. Analysis of SkillsBench reveals that current benchmarks only cover 39.90-43.98% of documented skill behavior constraints, indicating significant gaps between task success and comprehensive skill testing.
Researchers propose Essential Subspace Merging (ESM), a training-free method that combines multiple task-specific models into a single multi-task model by identifying and orthogonalizing principal component directions while suppressing interference-causing noise. The approach demonstrates that most inter-task interference stems from accumulated energy in non-essential directions rather than core task-relevant updates, enabling efficient model consolidation across multiple domains.
This paper addresses ABox abduction in description logic EL_bot by investigating hypotheses that satisfy multiple desired properties simultaneously under repair semantics. The research demonstrates that combining signature restrictions with optimality criteria often does not increase computational complexity, advancing the theoretical foundations of knowledge base repair.
Researchers introduce UBP2, a model-based reinforcement learning method that improves sample efficiency in preference-based learning by actively directing exploration through uncertainty quantification across reward, dynamics, and value functions. The approach achieves sublinear regret guarantees and demonstrates substantially higher sample efficiency than existing methods on benchmark tasks.
Researchers introduce KAPRO, a framework for evaluating whether LLM agents can accurately determine when to use external tools versus relying on internal knowledge. The study reveals that open-source models suffer from tool overuse due to pattern matching, while proprietary models show better self-awareness, highlighting a critical gap in current AI agent capabilities.
Researchers identify 'confidence laundering' as a critical failure mode in multi-component agent systems where upstream uncertainty gets masked by downstream components, leading to error amplification. They propose 'latent uncertainty' as a solution to preserve decision fragility across component interfaces rather than treating intermediate outputs as procedurally valid artifacts.
Researchers propose a quantum-assisted distributed AI framework for optimizing microgrid operations that combines renewable energy sources with storage and demand-response systems. The system uses quantum and classical solvers to solve dispatch problems within strict deadlines, achieving optimal results with 97.83% renewable utilization and zero missed deadlines in testing.
Researchers introduced PathLab, an AI-powered autonomous framework that translates natural language into computational pathology workflows, eliminating the need for programming expertise. The system demonstrated performance equivalent to expert implementations across 12 datasets while enabling non-technical domain experts to independently design and execute pathology studies.
A philosophical paper argues that AI should be understood as an indivisible monistic system rather than a collection of separate components like data and algorithms. This conceptualization carries significant implications for organizational structure, governance, and how enterprises integrate AI systems across technical, operational, and strategic domains.
Researchers compare four neural network architectures for factual knowledge propagation in question-answering systems, finding that repeated shared memory access enables out-of-distribution generalization ('grokking'), but only architectures with fine-grained addressable memory can effectively propagate edited facts. The study dissociates learning capability from editing affordance, revealing that looped computation and explicit memory mechanisms serve different functional purposes.
Researchers introduce FaraGen1.5, a scalable data pipeline for training computer use agents that combines live websites and synthetic environments with multiple verifiers. The resulting Fara1.5 family of agents achieves state-of-the-art performance across three model sizes (4B-27B parameters), with the 27B variant matching much larger proprietary systems on benchmark tasks.
Researchers investigate emergent misalignment (EM) in AI models, where narrow fine-tuning causes broad but uneven misalignment across evaluations. Through analysis of training dynamics, model priors, and data, they find that model architecture priors partially predict misalignment outcomes, learning schedules show limited influence on alignment improvement, and activation patterns between training and evaluation reveal significant overlap that correlates with misalignment propagation.
Researchers introduce Process-Reward Tactic Evolution, a training framework that enables LLM agents to reliably execute complex bioinformatics workflows in Galaxy by accumulating reusable tactics from verified workflow rollouts. The approach combines process verification, curriculum learning, and tactic libraries to improve long-horizon task completion, biological correctness, and execution efficiency compared to baseline methods.
Researchers introduce SignVLA, a real-time framework enabling robots to understand and execute manipulation tasks through sign language instructions. The system combines hand-landmark extraction, attention-enhanced LSTM networks, and vision-language-action models to create an accessible human-robot interaction interface for deaf and speech-impaired users.
Researchers conducted a systematic empirical study of intrinsic reward methods for code generation using reinforcement learning, finding that certainty-based approaches achieve early gains but inevitably collapse as models progressively shorten outputs and lose reasoning capability. The study reveals that pre-training with intrinsic rewards offers no significant improvement over training from scratch, challenging the transferability of these methods from mathematical reasoning to code generation tasks.
Researchers introduce αNeSy-CTM, a hybrid neurosymbolic framework combining Large Language Models with logical verification to automate clinical trial matching. The system achieves 30% relative improvement over zero-shot baselines by leveraging LLM language capabilities alongside formal symbolic reasoning to handle incomplete patient records and complex eligibility criteria.
Researchers introduce PAG-RCA, a framework for root cause analysis in complex systems that accounts for unobserved latent variables using Partial Ancestral Graphs. The methodology combines causal identification with partial identification bounds to diagnose system failures reliably even when data is scarce or incomplete, outperforming existing approaches on synthetic and real-world infrastructure benchmarks.
Researchers have introduced GRAIDES, an open-source data model designed to standardize how generative AI systems are evaluated and monitored across organizations. The framework addresses fragmentation in AI evaluation practices by centralizing observability and providing practical blueprints for assurance, with an initial case study demonstrating its application in local government.
A research paper demonstrates that organizing demonstration data hierarchically into labeled subgoals significantly improves LLM agent performance on ambiguous tasks, achieving 90.7% pass rates versus 76.7% for flat action logs. This finding provides concrete design guidance for Programming by Demonstration systems and broader procedural knowledge transfer to AI agents.
BioInsight is a multi-agent AI system that transforms static biomedical reports into interactive, evidence-centered interfaces for disease research. The system combines evidence retrieval, mechanistic reasoning, and citation normalization to help researchers inspect findings, assess uncertainty, and refine hypotheses more effectively than traditional text-based outputs.
Researchers introduce Beaver, an AI agent harness designed to extract structured information from scientific papers containing multimodal evidence (text, tables, figures). The system achieves 81.0 on the Gold-Referenced Attribute Score, outperforming frontier agents by 23 points, demonstrating that harness design—not just underlying models—is critical for complex information extraction tasks.
Researchers introduce Agentic Time Machine (TM), an infrastructure that reconstructs past web states to enable efficient evaluation of AI agents on event forecasting tasks. A multi-agent framework using this system achieves top performance on FutureX benchmarks and Polymarket predictions, demonstrating that offline evaluation correlates strongly with live forecasting results.
Researchers propose a 'negative knowledge' memory system for AI-assisted research that captures and structures failed experiments as reusable knowledge assets. The approach outperforms baseline AutoResearch systems while reducing token usage, and demonstrates transfer learning capabilities across different scientific problems in nonlinear PDE research.
Researchers introduce Coherence Under Commitment (CUC), a new evaluation framework that exposes a critical flaw in LLM logical reasoning: models can achieve coherence by refusing to make decisions rather than reasoning correctly. Testing on small language models reveals a stark trade-off where more decisive models contradict themselves frequently, while conservative models abstain from answering.
Researchers identify 'scientific amnesia' as a critical failure mode in continual DPO (Direct Preference Optimization) training pipelines where LLMs preserve learned behaviors but fail to accumulate reusable methodological knowledge across sequential training campaigns. Testing five strategy proposers on a 30-campaign benchmark reveals that most approaches degrade performance, with only conservative rule-based scheduling showing consistent improvement.
