Fix Your Classifier

PyTorch implementation of the fixed classifier described in "Fix your classifier: the marginal value of training the last weight layer" (ICLR-2018) by Elad Hoffer, Itay Hubara and Daniel Soudry.

This repository holds both random orthogonal classifier, and Hadamard classifier. They can be used to replace any nn.Linear module normally used for classification.
