Overview

This repo contains the PyTorch implementation of Moment Exchange (MoEx), described in the paper On Feature Normalization and Data Augmentation. For ImageNet and CIFAR experiments, we select Positional Normalization (PONO) as the feature normalization method.

Usage

Please follow the instructions in the README.md in each subfolder to run experiments with MoEx on CIFAR, ImageNet, and ModelNet10/40.

More information and relevant applications will be updated.
