Rater State Bias in RLHF Preference Data: An Audit FrameworkWe identify a structured confound in Reinforcement Learning from Human Feedback (RLHF). Pairwise preference labels are intended to reflect the compared outputs, but they may also reflect the rater's state during annotation. Under sustained stressful or distressing conditions, raters' preferences may shift over time. A…
↗Jul 21, 2026arXiv cs.AIDesign and Validation of a Lightweight 1D CNN for Affective Touch Classification in Soft Plush CompanionsSoft, sensorized companions offer a physically safe and emotionally intuitive interface for socially assistive technologies, yet their deformability and multichannel tactile sensing complicate the robust interpretation of human affect. This study presents a complete open-source MATLAB-based framework for the developme…
↗Jul 21, 2026arXiv cs.AISome Large Language Models Exhibit Consistent Risk AttitudesAs artificial intelligence systems are deployed in open-ended, high-stakes settings, a critical dimension remains unmeasured: how perceived risk is translated into action. We test whether large language models (LLMs) exhibit systematic and consistent risk attitudes under uncertainty. We introduce a cross-domain framew…
↗Jul 21, 2026arXiv cs.AIA Survey on GNN-based Link Prediction: Techniques, Applications, and ChallengesGraph Neural Networks (GNNs) have emerged as the leading paradigm for link prediction, enabling the inference of missing connections and the anticipation of potential future links. However, existing reviews lack systematic exploration specifically targeting underlying GNN architectures and diverse graph structures. To…
↗Jul 21, 2026arXiv cs.AIPlanFlip: Attacking Multi-Agent LLM Systems via Planning-Phase Prompt InjectionMulti-agent LLM systems increasingly rely on a Planner to decompose goals into sub-task sequences that downstream Executor and Critic agents execute and audit. We identify the planning phase as a critical attack surface: a single injection into the Planner's context achieves cascade amplification, corrupting all downs…
↗Jul 21, 2026arXiv cs.AIDeterministic Replay for AI Agent SystemsAI agent systems that couple large language models (LLMs) with external tools and APIs are inherently non-deterministic: LLM sampling variance, external API state, CDN infrastructure headers, and execution-environment noise collectively prevent any prior agent run from being faithfully re-executed. Existing observabil…
↗Jul 21, 2026arXiv cs.AIGenerative Ontology Induction: Domain-Agnostic Schema Discovery from Document Corpora Using Large Language ModelsOntology engineering remains a critical bottleneck in knowledge-intensive AI systems. Existing automated approaches either depend on predefined schemas, operate within narrow domains, or produce unstructured outputs unsuitable for downstream pipelines. We introduce Generative Ontology Induction (GOI), a domain-agnosti…
↗Jul 21, 2026arXiv cs.AIDemocratizing AI with Small Language Models: Structured Benchmarking and Parameter-Efficient Fine-Tuning for Local DeploymentAI democratization is not primarily a question of matching frontier-scale generality; it is a question of whether capable models can be selected, audited, and specialized under hardware and governance constraints that ordinary institutions can actually satisfy. This paper studies that problem through a controlled eval…

↗Jul 20, 2026arXiv cs.AICausal-Audit: Explicit and Auditable Graph-based Reasoning via Target-Aware Causal Chain ConstructionCausal and intervention-based question answering is fundamental to advancing large language models (LLMs) toward reasoning beyond surface-level correlations and understanding underlying causal mechanisms. However, existing LLM-based methods often rely on implicit language-level reasoning, resulting in opaque causal as…
↗Jul 20, 2026arXiv cs.AICura 1T: Specialized Model for Agentic HealthcareHealthcare spans high-stakes communication, expert reasoning, and workflow execution, yet specialized LLMs that cover these use cases together remain limited. A healthcare model must handle patient consultation, clinical reasoning over text and images, interactive diagnosis, and electronic health record (EHR) tool use…
↗Jul 20, 2026arXiv cs.AIAnovaX: A Local, Multi-Agent Voice Assistant with LLM Planning, Typed Executors, and Adaptive RecoveryDesktop voice assistants are still dominated by cloud pipelines that ship raw audio off the machine and expose a fixed set of skills. We describe AnovaX, a small local-first assistant that runs entirely on the user's computer and treats the desktop itself as its action surface. A single Python process wires together a…
↗Jul 20, 2026arXiv cs.AIPrecise but Uncoupled: Reviewer Precision Does Not Guarantee Critique Uptake in Multi-Agent Math ReasoningMany math- and science-oriented agent systems use hierarchical designs with specialized reviewer roles, assuming that a dedicated review stage should help turn wrong candidates into correct ones. We test this assumption on 4,181 verifier-grounded Omni-MATH problems using matched gpt-oss-120b actors. Collaboration adds…
