A Note on Connecting Barlow Twins with Negative-Samples-Free Contrastive Learning

I hope this work will be useful for your research 🥰

A large portion of the code is from this repo, which is a great resource for academic development. Note that we do not perform extensive hyper-parameters grid search and hence you may expect a performance boost after tuning some hyper-parameters (e.g., the learning rate).

The official implementation of Barlow Twins can be found here. We have also tried the HSIC_SSL in this official repo and we find similar performance (we tried on ImageNet-1K and CIFAR10) between HSIC_SSL and Barlow Twins' method.
