Reasoning as Gradient: Scaling MLE Agents Beyond Tree Search

Yifei Zhang, Xu Yang, Xiao Yang +8

LLM-based agents for machine learning engineering (MLE) predominantly rely on tree search, a form of gradient-free optimization that uses scalar validation scores to rank candidate…

OptPO: Optimal Rollout Allocation for Test-time Policy Optimization

Youkang Wang, Jian Wang, Rubing Chen +3

Test-time policy optimization enables large language models (LLMs) to adapt to distribution shifts by leveraging feedback from self-generated rollouts. However, existing methods re…
