The Past Is Not Past: Memory-Enhanced Dynamic Reward Shaping

Researchers introduce MEDS, a memory-enhanced reward shaping framework that addresses a critical reinforcement learning failure mode where language models repeatedly generate similar errors. By tracking historical behavioral patterns and penalizing recurring mistake clusters, the method achieves consistent performance improvements across multiple datasets and models while increasing sampling diversity.

MVR: Multi-view Video Reward Shaping for Reinforcement Learning

Researchers introduce Multi-View Video Reward Shaping (MVR), a new reinforcement learning framework that uses multi-viewpoint video analysis and vision-language models to improve reward design for complex AI tasks. The system addresses limitations of single-image approaches by analyzing dynamic motions across multiple camera angles, showing improved performance on humanoid locomotion and manipulation tasks.
