Such representations are useful for standard downstream tasks such as supervised learning and reinforcement learning, and for tasks such as transfer learning and zero-shot learning where humans excel but machines struggle (Lake et al, 2016). In this paper, we formulate the notion of "good" representation from a group-theoretic view using Higgins' definition of disentangled representation, and show that existing Self-Supervised Learning (SSL) only disentangles simple augmentation features such as rotation and colorization, thus unable to modularize the remaining semantics.
