摘要

The effectiveness of deep supervised learning heavily depends on the availability of large amounts of labeled data, which can be expensive to obtain. As a subset of unsupervised learning, self-supervised learning (SSL) has recently garnered significant attention due to its remarkable ability to learn useful features from large collections of unlabeled data. This survey provides a comprehensive review of various SSL methods with a specific focus on computer vision (CV). The reviewed SSL methods are categorized into three types based on their respective pretext tasks. In addition, the multi-view learning framework within the SSL is reviewed and discussed. Based on this framework, a novel method is proposed for learning minimal sufficient representation. Finally, future research directions of SSL are discussed.
