unicon-slssl's Introduction

UNICON-Noisy-Label

Official Implementation of the CVPR 2022 paper "UNICON: Combating Label Noise Through Uniform Selection and Contrastive Learning" https://arxiv.org/pdf/2203.14542.pdf

Example Run

After creating a virtual environment, run

pip install -r requirements.txt

Example run (CIFAR10 with 50% symmetric noise)

python Train_cifar.py --dataset cifar10 --num_class 10 --data_path ./data/cifar10 --noise_mode 'sym' --r 0.5

Example run (CIFAR100 with 90% symmetric noise)

python Train_cifar.py --dataset cifar100 --num_class 100 --data_path ./data/cifar100 --noise_mode 'sym' --r 0.9

This will throw an error as downloaded files will not be in proper folder. That is why they are needed to be manually moved to the "data_path".

Example Run (TinyImageNet with 50% symmetric noise)

python Train_TinyImageNet.py --ratio 0.5

Example run (Clothing1M)

python Train_clothing1M.py --batch_size 32 --num_epochs 200

Example run (Webvision)

python Train_webvision.py

Dataset

For datasets other than CIFAR10 and CIFAR100, you need to download them from their corresponsing website.
