Transfer RL across Observation Feature Spaces via Model-Based Regularization

no code implementations ICLR 2022 Yanchao Sun, Ruijie Zheng, Xiyao Wang, Andrew Cohen, Furong Huang

In many reinforcement learning (RL) applications, the observation space is specified by human developers and restricted by physical realizations, and may thus be subject to dramatic changes over time (e. g. increased number of observable features).
