Train from scratch

Use the following script to train our model on the AQA-7 dataset.

python run_net.py --exp_name your_exp_name \
  --gpu 0,1,2,3 --seed 0 --approach g_e_graph \
  --lambda_distill 9 --lambda_diff 0.7 \
  --replay --replay_method group_replay --memory_size 30 \
  --diff_loss \
  --aug_approach aug-diff --aug_mode fs_aug --num_helpers 7 --aug_scale 0.3\
  --save_graph --g_e_graph --fix_graph_mode no_fix \
  --save_ckpt\
  --optim_mode new_optim --lr_decay --num_epochs 200 --batch-size 16 --alpha 0.8 

Use the following script to train our model on the MTL-AQA dataset.

python run_net.py --exp_name your_exp_name \
  --gpu 0 --seed 0 --approach aug-diff \
  --lambda_distill 7 --lambda_diff 0.1 \
  --replay --replay_method group_replay --memory_size 30\
  --diff_loss \
  --aug_approach aug-diff --aug_mode fs_aug --num_helpers 7 --aug_scale 0.7 \
  --optim_mode new_optim --lr_decay --num_epochs 200 --batch-size 16;

Use the following script to train our model on the BEST dataset.

python run_net.py --exp_name your_exp_name \
  --gpu 0,1,2,3 --seed 0 --approach g_e_graph \
  --feat_distill --lambda_distill 7 \
  --replay --replay_method group_replay --memory_size 30 \
  --diff_loss --aug_approach aug-diff --aug_mode fs_aug --num_helpers 7 --aug_scale 0.3 --lambda_diff 10 \
  --g_e_graph --fix_graph_mode no_fix --alpha 0.6\
