PalmLeaf-VQA: A Multi-Script Visual Question Answering Benchmark for Historical Palm-Leaf Manuscript Understanding Across Diverse Regions

PalmLeaf-VQA provides a standardized benchmark for advancing culturally grounded and layout-aware multimodal document analysis and reveals substantial limitations in current MLLMs for rare-script, degraded-layout, and preservation-oriented document understanding.

From Hand-Crafted to LLM-Based Variation Operators in Metaheuristics: A Tutorial

Large language models (LLMs) are increasingly being employed as variation operators in metaheuristics, generating or modifying candidate solutions, heuristics, or programs inside iterative search loops. This shift reframes variation as a model call conditioned on different types of information. We introduce an operator...

ChestPheNoT: Deployable, Auditable Label-Status-Evidence Extraction from Radiology Reports

CHESTPHENOT is a compact 0.5-3B language model that jointly extracts finding labels, three-class status (present/absent/uncertain), and verbatim supporting evidence spans and demonstrates that locally deployable models can provide competitive and directly auditable radiology-report extraction without relying on externa...

Shockingly Simple Self-retrospection Improves Agentic Models Without RL

Retrospection-Only Fine-Tuning (ROFT), a minimal online procedure designed to isolate the effect of explanation-only training on subsequent behavior, is studied, showing that learning to explain can also improve learning to do and motivating further study of explanation-to-action transfer.

Reinforcing Agentic Creativity in Scientific Ideation with Night Science

AI Night-Scientist is introduced, an agentic framework that uses reinforcement learning to teach models when and how to depart from predictable reasoning to suggest creativity is a learnable, multi-level ability that can be shaped to help researchers reach ideas beyond those typically explored by LLMs.

TCSAlgBench: Benchmarking Automated Proving for Research-Level Theoretical Computer Science

TCSAlgBench provides a refreshable testbed for measuring progress in model reasoning and studying how agent workflows support research-level proof discovery, and evaluates ten model configurations from four families under direct inference and prover-verifier discussion, and compares four agent workflows under matched m...

Share-Borne AI Virus: Memory-Hopping Attacks Across LLM Agents

This work introduces artifact-mediated propagation, where adversarial content introduced through an artifact is stored in an assistant's persistent memory, reproduced in a subsequently created artifact, and acquired by another assistant that later reads it.

Representation Alignment as a Bottleneck in LLM-Based Retrosynthesis Planning

While LLMs show promise in general reasoning, symbolic planning in chemistry remains a bottleneck. Direct ''SMILES-to-PDDL'' attempts fail because they force models to juggle chemical analysis and planning-language structuring simultaneously. We hypothesize that this failure stems from a lack of intermediate abstractio...

Self-Adapting Group of Experts for Multi-Agent Reasoning

This work introduces SAGE (Self-Adapting Group of Experts), a training-free framework that uses answer agreement, prefix consistency, and reciprocal peer review to select a strategy donor and transfers the selected donor's reasoning strategy to the other agents while preserving their original roles.

Jailbreaks for Black-Box Uncertainty Quantification in Large Reasoning Models

While Large Reasoning Models (LRMs) excel at complex reasoning, alignment through reinforcement learning often induces systemic overconfidence. In production environments, where logits may be unavailable, robust black-box uncertainty quantification (UQ) is essential for trustworthiness and safety. Focusing on question-...

EvoIn: Bridging Evolution and Internalization for Agent Fine-Tuning

EvoIn is an agent fine-tuning framework that bridges evolution and internalization, and consistently enables agents to learn stronger decision-making procedures, raising the pass rate by 10.9 points in-domain and by 9.2 points out-of-domain.

5W1H+Which: Context-Valid Semantic Indexing with Progressive Ontology Binding

This work proposes 5W1H+Which, a semantic indexing design that separates content extraction from ontology binding, and distinguishes business valid time, system knowledge time, and operational traces, and uses dependency records to support binding revalidation and the maintenance of derived conclusions.
