Exploring-Weight-Balancing-on-Long-Tailed-Recognition-Problem (ICLR2024)

Code Description

This repository comprises code for LTR. Primarily, one can conduct training (or logit adjustment) and assess the model by executing first.py and second.py at the top level.

first.py: Code for the initial stage of training.
second.py: Code for the subsequent stage of training or logit adjustment.

This repository is based on the paper and repository of Alshammari et al. Please refer to them as well.

How to Execute

Setup environment. Refer to Requirement.
Prepare datasets. If you want to experiment with CIFAR, this program automatically download them to the datasets directory. If you want to use ImageNet or other datasets, place them in the datasets folder beforehand. The location can be modified in utils/conf.py.
Execute. Run the program by executing first.py or second.py. You can reproduce experiments detailed in our paper by specifying the JSON file path in the jsons directory. For instance:

python first.py --seeds 0 --json_path "./jsons/Cifar100/first.json"

python second.py --seeds 0 --json_path "./jsons/Cifar100/second.json"

Check the results by examining the standard output and the exp folder.

Requirement

Install pip, Python, and PyTorch. Our environment specifications are depicted below. Other versions might function, albeit reproducibility of results cannot be guaranteed.
- Python version: Python 3.6.8
- PyTorch verion: 1.10.1+cu113
Install the libraries via pip using the following command.

pip install -U scikit-image pandas seaborn ipykernel scikit-learn tensorboard
