Pytorch Implementation of Class-Balanced Distillation for Long-Tailed Visual Recognition by Ahmet Iscen, André Araujo, Boqing Gong, Cordelia Schmid

---

Note:

- Implemented only for ImageNetLT
- `normal_teachers` is the `Standard model` from the paper
- `aug_teachers` is the `Data Augmentation model` from the paper

Things to do before you run :

• Change the data_root for your dataset in main.py.
• If you are using wandb logging (Weights & Biases), make sure to change the wandb.init in main.py accordingly.

How to use?

• Easy to use : Check this script - multi_runs.sh
• Train the normal teachers :

python main.py --experiment=0.1 --seed=1 --gpu="0,1" --train --log_offline

• Train the augmentation teachers :

python main.py --experiment=0.2 --seed=1 --gpu="0,1" --train --log_offline

• Train the Class Balanced Distilled Student :

python main.py --experiment=0.3 --alpha=0.4 --beta=100 --seed=$seeds --gpu="0,1" --train --log_offline --normal_teacher="10,20" --aug_teacher="20,30"

Arguments :

(General)

• --seed: Seed of your current run
• --gpu: GPUs to be used
• --experiment: Experiment number (Check libs/utils/experiment_maker.py for more details)
• --wandb_logger: Does wandb Logging
• --log_offline: Does offline Logging
• --resume: Resumes the training if the run crashes

(Specific to Distillation and Student's training)

• --alpha: Weightage between Classifier loss and distillation loss
• --beta: weightage for the Cosine Similarity between teachers and student
• --normal_teachers: What all seed of norma teachers do you want to use? If you want to use only augmentation teachers, just don't use this argument. It is None by default.
• --aug_teachers: What all seed of augmented teachers do you want to use? If you want to use only normal teachers, just don't use this argument. It is None by default.
