Title: Temporal Change Sensitive Representation for Reinforcement Learing. Abstract: Image-based deep reinforcement learning has made a great improvement recently by combining state-of-the-art reinforcement learning algorithms with self-supervised representation learning algorithms. However, these self-supervised representation learning algorithms are designed to preserve global visual information, which may miss changes in visual information that are important for performing the task. To resolve this problem, self-supervised representation learning specifically designed for better preserving task relevant information is necessary. Following this idea, we introduce Temporal Change Sensitive Representation (TCSR), which is designed for reinforcement learning algorithms that have a latent dynamic model. TCSR enforces the latent state representation of the reinforcement agent to put more emphasis on the part of observation that could potentially change in the future. Our method achieves SoTA performance in Atari100K benchmark.
