Model Diversity in RL
Alex discusses the importance of maintaining model diversity during reinforcement learning (RL) fine tuning, highlighting that while supervised fine tuning may lead to a quick decay in diversity, RL methods can preserve it. He explains how expanding the training data with diverse inputs contributes to better outputs and shares insights from classical RL strategies like auto curricula and prioritized level replay, although the latter didn't yield the expected generalization improvements.In this clip
