WebWe provide a hypothesis on the implication of stop-gradient, and further show proof-of-concept experiments verifying it. Our "SimSiam" method achieves competitive results on ImageNet and downstream tasks. We hope this simple baseline will motivate people to rethink the roles of Siamese architectures for unsupervised representation learning. Webillustrate this “SimSiam” method in Figure 1. Thanks to the conceptual simplicity, SimSiam can serve as a hub that relates several existing methods. In a nut-shell, our method can …
