Deep-INFOMAX

This is a pytorch implementation of Deep-INFOMAX.

original paper : Learning deep representations by mutual information estimation and maximization.

  1. DuaneNielsen/DeepInfomaxPytorch

pytorch. model definition and training script only without clustering example. our code is mainly based on this repository. Thanks!

  1. rcalland/deep-INFOMAX

chainer. model definition and traning script with (knn?) clustering example on CIFAR10. Better documentation.

  1. 深度学习中的互信息:无监督提取特征

instead Adversarial training, this blog implements gaussian distribution as prior (similar to VAE). worth a try.

sample result

after training 100 epochs with Adam(lr=1e-4), we see that the encoder is able to distinguish "animals" and non-living things. (among 100 test images)

top row : selected image; middle row : top 10 images with smallest L1 loss; bottom row : top 10 images with largest L1 loss.
