Research Experience

Transferable Proximal Policy Optimization for Multitask Reinforcement Learning

University of California, Irvine — Machine Learning and Scientific Computing Laboratory (MLSC Lab)  |  Sep. 2024 – Present

• Strengthened a baseline proximal policy optimization framework to share experience across agents when training resources are limited.
• Proposed an automatic auxiliary-task selection strategy that adapts to each primary task during training.
• Introduced a fine-tuning stage that improves multi-task performance and mitigates catastrophic forgetting.
• Analyzed the effect of mini-batch sizing on training stability and sample efficiency across tasks.
