AceGRPO: Adaptive Curriculum Enhanced Group Relative Policy Optimization for Autonomous Machine Learning Engineering
Researchers introduce AceGRPO, a new reinforcement learning framework for Autonomous Machine Learning Engineering that addresses behavioral stagnation in current LLM-based agents. The Ace-30B model trained with this method achieves 100% valid submission rate on MLE-Bench-Lite and matches performance of proprietary frontier models while outperforming larger open-source alternatives.
