MixMatch

This is an unofficial PyTorch implementation of MixMatch: A Holistic Approach to Semi-Supervised Learning. The official Tensorflow implementation is here.

Now only experiments on CIFAR-10 are available.

This repository carefully implemented important details of the official implementation to reproduce the results.

Requirements

Python 3.6+
PyTorch 1.0
torchvision 0.2.2 (older versions are not compatible with this code)
tensorboardX
progress
matplotlib
numpy

Usage

Train

Train the model by 250 labeled data of CIFAR-10 dataset:

python train.py --gpu <gpu_id> --n-labeled 250 --out cifar10@250

Train the model by 4000 labeled data of CIFAR-10 dataset:

python train.py --gpu <gpu_id> --n-labeled 4000 --out cifar10@4000

Monitoring training progress

tensorboard.sh --port 6006 --logdir cifar10@250
