报告摘要:
The majority reinforcement learning (RL) algorithms are largely categorized as model-free and model-based through whether a world model is learned in the algorithm. However, both of these two categories have their own issues, especially incorporating with function approximation: the exploration with arbitrary function approximation in model-free RL algorithms is difficult, while optimal planning becomes intractable in model-based RL algorithms with neural nonlinear world models.
In this talk, I will present our recent work on exploiting the power of representation in RL to bypass these difficulties, while enjoys best of both worlds. Specifically, we designed practical algorithms for extracting useful representations from world model, with the goal of improving statistical and computational efficiency in exploration vs. exploitation tradeoff and empirical performance in RL. We provide rigorous theoretical analysis of our algorithm, and demonstrate the practical superior performance over the existing state-of-the-art empirical algorithms on several benchmarks.
