Overview

M2m: Imbalanced Classification via Major-to-minor Translation

This repository contains code for the paper "M2m: Imbalanced Classification via Major-to-minor Translation" by Jaehyung Kim*, Jongheon Jeong* and Jinwoo Shin.

Dependencies

python3
pytorch >= 1.1.0
torchvision
tqdm

Scripts

Please check out run.sh for all the scripts to reproduce the CIFAR-10-LT results reported.

Training procedure of M2m

Train a baseline network g for generating minority samples

python train.py --no_over --ratio 100 --decay 2e-4 --model resnet32 --dataset cifar10 \
--lr 0.1 --batch-size 128 --name 'ERM' --warm 200 --epoch 200

Train another network f using M2m with the pre-trained g

python train.py -gen -r --ratio 100 --decay 2e-4 --model resnet32 --dataset cifar10 \
--lr 0.1 --batch-size 128 --name 'M2m' --beta 0.999 --lam 0.5 --gamma 0.9 \
--step_size 0.1 --attack_iter 10 --warm 160 --epoch 200 --net_g ./checkpoint/pre_trained_g.t7

We also provide a pre-trained ResNet-32 model of g at checkpoint/erm_r100_c10_trial1.t7, so one can directly use M2m without pre-training as follows:

python train.py -gen -r --ratio 100 --decay 2e-4 --model resnet32 --dataset cifar10 \
--lr 0.1 --batch-size 128 --name 'M2m' --beta 0.999 --lam 0.5 --gamma 0.9 \
--step_size 0.1 --attack_iter 10 --warm 160 --epoch 200 --net_g ./checkpoint/erm_r100_c10_trial1.t7

Comments

train M2m

great work! it seems to should add "--resume" when training M2m. (load ckpt_g) friendly warning. by the way, do you apply M2m on larger dataset, such as Imagenet?

Could you provide the processed CelebA-5 dataset?

Hi,

Thanks for your interesting work. I'd like to reproduce the experiments on CelebA-5, but it needs to be processed based on the official version as described in your paper. Could you please share a copy of the processed dataset or the script for processing?

Best Regards, Hongxin

Loss function used to train baseline classifier g

Hello,

Great work guys,

I have a small question regarding the baseline classifier g.

Which loss are you using to train it? Is it Vanilla CE Loss? Because when analyzing accuracy per class on the unbalanced training data using the baseline classifier g with the weights that you provided, I found these already good accuracy values for unbalanced training: [99.8200, 99.8332, 99.2205, 97.8644, 98.6047, 97.1576, 97.8448, 99.2806, 97.5904, 96.0000].

Does it make sense to train it on more sophisticated losses like Weighted CE or so, to allow the model pick the features related to the minority samples better? Because on my dateset, the baseline classifier trained with CE performs really badly with a low accuracy near 5% on the minority sample of the training set. i.e. How well should the baseline classifier perform on the minority samples of the training data?

It would be great if you share the training procedure for reproducing the baseline classifier g (schedule, sampling methods, loss..).

I look forward to hearing from.

Many many thanks Best, Hssan

How to reproduce the results on CIFAR10 and CIFAR100?
Hello All,

This is Sourav Das, currently working as a Project-Linked Person at Indian Statistical Institute, Kolkata.

I went through your CVPR 2020 paper, titled "M2m: Imbalanced Classification via Major-to-minor Translation" and would like to reproduce the result on CIFAR10 and CIFAR100 datasets.

I cloned the GitHub repo https://github.com/alinlab/M2m but I don't know

In which path to keep the CIFAR10 or CIFAR100 datasets?

In which format should the datasets be present?

Will it run with CIFAR10 and CIFAR100 datasets, directly downloaded from the site: https://www.cs.toronto.edu/~kriz/cifar.html or do I need to do some pre-processing to the datasets?

Awaiting an early response from you.

Thanks & Regards, Sourav Das

Guidence is needed to reproduce the results ? ?

i have recently learnt python and went through the some MOOCS of machine learning and deep learning. I have downloaded the whole code from this site. Any one kindly guide me how to run the code and reproduce the results ??

Parameter for cifar10/100-r10/100

Hi, great work! I have trained cifar10_r10, cifar100_r10 and cifar100_r100. ALL the bACC of 3 ERM models is better but cifar100_r100 M2m model has SOTA performance. Can you tell me how to do to improve my model performance of c10_r10 and c100_r10?
