Contrastive Learning as Goal-Conditioned Reinforcement Learning [PDF]

open access: yesNeural Information Processing Systems, 2022
In reinforcement learning (RL), it is easier to solve a task if given a good representation. While deep RL should automatically acquire such good representations, prior work often finds that learning representations in an end-to-end fashion is unstable ...
