Generative Online Reinforcement Learning

ICML 2026poster

Reinforcement learning (RL) faces a persistent tension: policies that are stable to optimize (e.g., Gaussians) are often too simple to represent the multimodal action distributions required for complex control. Conversely, expressive generative policies—such as diffusion and flow matching—are freque…

Uncertainty-Aware Iterative Preference Optimization for Enhanced LLM Reasoning

ACL 2025long

Direct Preference Optimization (DPO) has recently emerged as an efficient and effective method for aligning large language models with human preferences. However, constructing high-quality preference datasets remains challenging, often necessitating expensive manual or powerful LM annotations. Addit…
