• Title: Environment Design for Inverse Reinforcement Learning
• Authors: Thomas Kleine Buening, Victor Villin, Christos Dimitrakakis,
• Abstract summary: Current inverse reinforcement learning methods that focus on learning from a single environment can fail to handle slight changes in the environment dynamics. In our framework, the learner repeatedly interacts with the expert, with the former selecting environments to identify the reward function. This results in improvements in both sample-efficiency and robustness, as we show experimentally, for both exact and approximate inference.

• Abstract: Learning a reward function from demonstrations suffers from low sample-efficiency. Even with abundant data, current inverse reinforcement learning methods that focus on learning from a single environment can fail to handle slight changes in the environment dynamics. We tackle these challenges through adaptive environment design. In our framework, the learner repeatedly interacts with the expert, with the former selecting environments to identify the reward function as quickly as possible from the expert's demonstrations in said environments. This results in improvements in both sample-efficiency and robustness, as we show experimentally, for both exact and approximate inference.

  We develop an inverse dynamics state representation learning objective to align the expert environment and the learning environment. With the abstract state representation, we design an effective reward function, which thoroughly measures the similarity between behavior data and expert data. Our approach can achieve a near-expert performance in most environments, and significantly outperforms the state-of-the-art visual IL methods and robust IL methods.

  We propose a task-agnostic method to identify observed/hidden states that are representative of a given level. The outcome of this method is then utilized to characterize the diversity between two levels, which as we show can be crucial to effective performance. In addition, to improve sampling efficiency, we incorporate the self-play technique that allows the environment generator to automatically generate environments that are of great benefit to the training agent.
