GGD

The core of GGD is to decompose the CE loss of GGE. The pytorch implementation is

loss = -(logits.log_softmax(-1) * labels).mean() + weight * (logits.log_softmax(-1) * bias * labels).mean()

Biased-MNIST

Biased-MNIST is produced the same with Re-bias. Run the notebook in the MNIST folder. Modify data_label_correlation for different bias level.

VQA-CP

Codes for VQA-CP is updated in GGE. To train a model with new GGD-CR, set import base_model_sfce in mian.py and run

CUDA_VISIBLE_DEVICES=0 python main.py --dataset cpv2 --mode gge_iter --debias ce_decompose --topq 1 --topv -1 --qvp 5 --output [] 

Adversarial SQuAD

The experiment for AdQA is provided in squad folder. The code is modified from squad.
