VRPO: Rethinking Value Modeling for Robust RL under Noisy Supervision in LLM Post-Training

Researchers propose VRPO, a reinforcement learning framework that strengthens value modeling to handle noisy reward signals in large language model post-training. The approach uses auxiliary losses and information bottleneck techniques to enable value models to filter noise and generate more reliable advantage estimates, outperforming standard methods like PPO and GRPO across dialogue, math, and QA tasks.

PACE: Anytime-Valid Acceptance Tests for Self-Evolving Agents

Researchers introduce PACE, a statistical testing framework that prevents self-evolving AI agents from committing false improvements to their own prompts and workflows. Unlike naive greedy acceptance rules that accumulate errors through repeated testing, PACE uses sequential hypothesis testing to distinguish genuine improvements from noise, reducing harmful modifications by 30-42% while maintaining accuracy at lower computational cost.

Training-Free Intelligibility-Guided Observation Addition for Noisy ASR

Researchers propose a training-free method for improving automatic speech recognition in noisy environments by intelligently fusing noisy and speech-enhanced audio based on intelligibility estimates. The approach eliminates the need for trained neural predictors, reducing complexity while maintaining robustness across diverse speech enhancement and ASR model combinations.

WISTERIA: Learning Clinical Representations from Noisy Supervision via Multi-View Consistency in Electronic Health Records

WISTERIA is a machine learning framework that improves clinical AI by treating noisy medical labels as uncertain observations rather than ground truth. By enforcing consistency across multiple weak supervision sources and incorporating medical ontologies, the method achieves better generalization across healthcare institutions and demonstrates robustness to label noise.
