DeiT-LT: Distillation strikes back for Vision Transformer training on Long-Tailed datasets

This repository contains the training, evaluation codes and checkpoints for the paper DeiT-LT: Distillation strikes back for Vision Transformer training on Long-Tailed datasets accepted at CVPR 2024.

Usage

1. Clone the respository.

git clone https://github.com/val-iisc/DeiT-LT.git

2. CIFAR-10 and CIFAR-100 datasets are downloaded on its own through the code. However, in case of Imagenet-LT and iNaturalist-2018, download these datasets from the given links.

3. Create the conda environment and activate it.

conda env create -f environment.yml
conda activate deitlt

4. Download the teacher models as given in Results table.

5. Run the corresponding training script for any dataset after adding teacher path in the script file for the argument --teacher-path. For example:

bash sh/train_c10_if100.sh
bash sh/train_imagenetlt.sh

6. For evaluation a DeiT-LT checkpoint, run the eval bash script for the corresponding dataset. Ensure that the checkpoint path is provided to the script for the argument --resume. For example:

bash sh/eval_c10.sh
bash sh/eval_imagenetlt.sh
