Plan2Explore: Active model-building for self-supervised visual reinforcement learning

To operate successfully in unstructured open-world environments, autonomous intelligent agents need to solve many different tasks and learn new tasks quickly. Reinforcement learning has enabled artificial agents to solve complex tasks both in simulation and real-world. However, it requires collecting large amounts of experience in the environment for each individual task. Self-supervised reinforcement learning has emerged as an alternative, where the agent only follows an intrinsic objective that is independent of any individual task, analogously to unsupervised representation learning. After acquiring general and reusable knowledge about the environment through self-supervision, the agent can adapt to specific downstream tasks more efficiently.
