Curriculum by Smoothing (NeurIPS 2020)

The official PyTorch implementation of Curriculum by Smoothing (NeurIPS 2020, Spotlight).

For any questions regarding the codebase, please send a message at: [email protected]

USAGE: Simply use the code by running:

python3 main.py --dataset --alg --data

For example, to train a ResNet on CIFAR10 and the data is saved in ./data/, we can run:

python3 main.py --dataset cifar10 --alg res --data ./data/

For new expeiments it is important to tune the following hyperparameters:

--std --std_factor --epoch

    Question on CBS Performance

    Hi, thanks for the interesting research / technique. I was trying to reproduce it and ran into a potential issue and was wondering if you could help shed some light on whether this is expected behavior. Looking at your training code, it seems that there is no pipeline data augmentation happening (except for a Normalize). When I do the same, I see large accuracy performance gains when using CBS on ciFAIR100 (blue vs orange below). However, looking at the CE graph it seems like the training is severely overfitting. I tried adding a simple 50% horizontal flip data augmentation during training, and the performance gains offered by CBS virtually disappeared (green vs brown). When I added slightly more augmentation (expand&crop + cutout) CBS actually performed worse than normal training (purple vs orange). Any thoughts on whether this is the expected behavior or why this might be happening?
