Why does KDDAug make baseline worse

[zhongshsh]

Baseline (updn, v2)

I run the following code:

CUDA_VISIBLE_DEVICES=0 python main.py --dataset v2 --mode updn --debias none --output v2_updn --seed 0

and get the following log:

[ItemZheng]

Which teacher did you use？How abont the performanc of ID teacher and OOD teacher on VQA v2 dataset?

[zhongshsh]

I train the teacher by following the README. Specifically, use the code :

CUDA_VISIBLE_DEVICES=0 python main.py --dataset v2 --mode q_v_debias --debias learned_mixin --topq 1 --topv -1 --qvp 5 --output v2_lmh_css --seed 2048

Then I assign new answer

CUDA_VISIBLE_DEVICES=0 python assign_answer.py --dataset v2 --name other --split low --teacher_path logs/v2_lmh_css/model.pth

[ItemZheng]

For VQA v2, I may train the teacher by following command:

CUDA_VISIBLE_DEVICES=0 python main.py --dataset v2 --mode q_v_debias --debias learned_mixin --topq 1 --topv -1 --qvp 9 --output v2_lmh_css --seed 2048 --epoch 40

You can try again.

[zhongshsh]

I train the teacher by :

CUDA_VISIBLE_DEVICES=4 python main.py --dataset v2 --mode q_v_debias --debias learned_mixin --topq 1 --topv -1 --qvp 9 --output v2_lmh_css_issue --seed 2048  --epoch 40
