Introduction

Mixup is a generic and straightforward data augmentation principle. In essence, mixup trains a neural network on convex combinations of pairs of examples and their labels. By doing so, mixup regularizes the neural network to favor simple linear behavior in-between training examples.

This repository contains the implementation used for the results in our paper (https://arxiv.org/abs/1710.09412).

Requirements and Installation

• A computer running macOS or Linux

• For training new models, you'll also need a NVIDIA GPU and NCCL

• Python version 3.6

• A PyTorch installation

Training

Use python train.py to train a new model. Here is an example setting:

$ CUDA_VISIBLE_DEVICES=0 python train.py --lr=0.1 --seed=20170922 --decay=1e-4
