Researchers propose Global-Local Uncertainty (GLU), a new method for quantifying uncertainty in large language models by combining hidden-state geometric entropy with token-level signals. The approach successfully identifies confident-but-wrong predictions that existing token-only methods miss, offering improved reliability assessment across multiple model families.
Researchers identify two critical failure modes in deep multi-agent reinforcement learning applied to continuous pricing markets: tacit collusion between DDPG agents and actor-critic instability at high event rates. While asynchronous pricing and latency reduce collusion by up to 48%, the fix remains partial and breaks down under high-frequency conditions, revealing fundamental limitations in current MARL approaches for market simulation.
Researchers introduce SHAPE, a novel expert pruning framework for Sparse Mixture-of-Experts (MoE) language models that reduces memory requirements by up to 40% without retraining. Unlike traditional pruning methods that evaluate experts independently, SHAPE models expert cooperation using game theory, identifying which expert combinations matter most for model performance.
Researchers introduce PreAct-Bench, a benchmark for evaluating LLMs' ability to predict unethical behavior from partial action trajectories before harmful actions occur. The study reveals that predictive monitoring remains a significant challenge even for advanced models, highlighting a critical gap in proactive AI safety mechanisms.
Researchers introduce Engram, an open-source memory engine for LLM agents that achieves 83.6% accuracy on long-context tasks using only 9.6k tokens versus 79k for full-history baselines, demonstrating that selective retrieval outperforms exhaustive context replay while reducing computational costs by 8x.
Researchers introduced IDP-Bench, the first benchmark evaluating how well large language models protect interdependent privacy—where one person's data can be revealed by others without consent. Testing eight open-source LLMs revealed strong performance in recognizing data co-ownership but significant weaknesses in understanding contextual integrity parameters and judging sharing appropriateness, with smaller models showing particular vulnerability to prompt sensitivity.
Researchers have developed TS-LFO, an attack method that successfully bypasses copyright protection systems in AI image generation models. The technique uses two-stage optimization to restore the mapping between images and their latent representations, defeating current state-of-the-art defenses and outperforming existing copyright-stealing attacks.
Researchers introduce IntentKV, a learned KV cache pruning technique that optimizes memory usage for multi-turn LLM agents without modifying the base model. The method achieves 23-30% reductions in peak request tokens and up to 92.6% fewer KV reads under tight memory budgets, addressing a critical bottleneck in long-horizon agent inference.
Researchers propose the first application of split conformal prediction to neural operators for physics simulation, enabling distribution-free uncertainty quantification with formal coverage guarantees. The method achieves 89.1% empirical coverage on heat conduction benchmarks while providing spatially adaptive prediction intervals, addressing a critical gap in deploying AI models for safety-critical engineering applications.
Researchers introduce Sigma-Branch, a neural network restructuring framework that reduces per-inference active parameters by 58-60% while maintaining full model capacity in memory. The approach uses hierarchical routing and binary tree architecture to enable efficient edge deployment without permanent model compression trade-offs.
Researchers introduce Entropy-Guided Power Sampling (EGPS), a novel training-free sampling method that accelerates reasoning in base language models by targeting high-entropy decision points rather than uniformly sampling across sequences. The technique achieves up to 12.6x speedup on mathematical and coding benchmarks while maintaining or improving accuracy, addressing fundamental inefficiencies in existing MCMC sampling approaches.
Researchers propose improved post-training quantization techniques for large language models using quantile-robust scaling policies and learned channel scales, demonstrating 18.5% error reduction on LLaMA-3.2-1B under W4A4 quantization. The work addresses activation quantization challenges caused by outlier-dominated channels, offering practical efficiency improvements for LLM deployment without requiring full model retraining.
Researchers introduce the 'strategic confinement problem,' extending Lampson's classical confinement theory to scenarios where communicating parties are strategic agents with shared coordination resources. The work demonstrates that information-theoretic bounds on communication capacity may fail to constrain the harmful outcomes strategic agents can jointly achieve through covert channels, particularly in systems of learned AI agents.
Researchers present GitInject, a framework demonstrating prompt injection vulnerabilities in AI-powered CI/CD pipelines used by major tech companies. The study reveals that all tested AI providers are susceptible to attacks that could enable credential theft, code manipulation, and supply chain compromise through GitHub workflows.
Researchers introduce 3SPO (State-Score-Supervised Policy Optimization), a reinforcement learning algorithm that optimizes LLM agent policies at each step rather than after complete episodes, addressing credit assignment challenges in sparse-reward environments. Experiments demonstrate 22.6% improvement over existing methods on ALFWorld benchmarks with 2.4x more state exploration and 1.8x faster convergence.
Researchers propose Generalized-CVO, a fast point cloud registration method using second-order Riemannian optimization that achieves 10x speedup over previous approaches. The technique demonstrates significant improvements in LiDAR tracking with >55% drift reduction in sparse environments and enhanced robustness on object registration benchmarks.
Researchers introduce VFUSE, a mechanistic interpretability tool using sparse autoencoders to audit protein design models for hazardous features. The approach successfully identifies virulent design patterns in popular open-weight models like RoseTTAFold3 and RFDiffusion3, achieving up to 0.84 AUROC detection rates while maintaining model performance.
Researchers introduce τ-Rec, a new benchmark for evaluating conversational AI recommender systems that replaces subjective LLM-based judging with verifiable, measurable rewards. Testing across nine model configurations reveals a critical reliability gap, with even top-performing models achieving only ~57% accuracy on single-attempt tasks, exposing significant limitations in current agentic AI deployment.
Researchers demonstrate that AI-assisted peer review systems are vulnerable to simple adversarial attacks, with superficial abstract rephrasing increasing acceptance ratings by up to 1.31 points on a 10-point scale without changing underlying scientific content. The low-cost manipulation ($1, 5 minutes) reveals systemic risks in AI-mediated scientific evaluation and raises concerns about authors optimizing for algorithmic judgment rather than merit.
Researchers present a comprehensive OS-centered privacy framework arguing that local AI processing alone does not guarantee privacy, as on-device models can still aggregate sensitive data, retain embeddings, invoke cloud services, and emit telemetry. The framework provides a threat model, risk taxonomy, and audit rubric, demonstrating that meaningful privacy depends on constrained information flow, bounded authority, and auditable governance rather than deployment location.
Researchers propose Dropout-GRPO, a method that addresses a fundamental limitation in training latent-reasoning language models by introducing structured stochasticity through dropout masks. The technique enables Group Relative Policy Optimization to work effectively with continuous hidden states rather than discrete tokens, improving performance on mathematical reasoning tasks.
