# CFNet
[](https://paperswithcode.com/sota/visual-question-answering-on-tvqa?p=cfnet-learning-with-collaborative-filtering-for)
This repository contains code for reproducing our paper "Learning With Collaborative Filtering For Visual Question Answering" presented at ICCV2021.
## Requirements
The code was tested under Python version `>=3.6`. Please install required packages by
pip install -r requirements.txt
We use PyTorch `>=1.7` as deep learning framework.
## Data preparation
We follow [Pythia](https://github.com/facebookresearch/Pythia) for preparing TVQA dataset.
cd datasets/tvqa/
python prepare_tvqa.py --data_dir /path/to/tvqa/data --output_dir /path/to/prepared/tvqa
We also use IMDB dataset as auxiliary dataset for training CFNet.
cd datasets/imdb/
python prepare_imdb.py --data_dir /path/to/imdb/data --output_dir /path/to/prepared/imdb
## Training
### TVQA
To train CFNet using TVQA dataset only (i.e., not using IMDB dataset), run
cd scripts/tvqa/
python train.py --tvqa_dir /path/to/prepared/tvqa --tvqa_split trainval --model cfnet --batch_size_per_gpu $N$ --num_workers $M$ --num_gpus $K$ --max_epoch $E$ --lr $L$ --output_dir /path/to/output/dir
where $N$ denotes batch size per GPU (per batch size = $N times K$), $M$ denotes number of workers used for loading data (per process), $K$ denotes number of GPUs used for training (per process), $E$ denotes maximum epoch number (set `--max_epoch -1` if training without early stopping), $L$ denotes initial learning rate (if using Adam optimizer).
### Auxiliary data
To train CFNet using TVQA+IMDB datasets (i.e., using IMDB dataset as auxiliary data), run
cd scripts/tvqa/
python train.py --tvqa_dir /path/to/prepared/tvqa --tvqa_split trainval
--imdb_dir /path/to/prepared/imdb
--model cfnet_auxiliary
--batch_size_per_gpu $N$ --num_workers $M$ --num_gpus $K$
--max_epoch $E$
--tvqa_train_steps_per_epoch $S_T$
--imdb_train_steps_per_epoch $S_I$
--lr_tvqa_train $L_T$
--lr_imdb_train $L_I$
--output_dir /path/to/output/dir
where `--tvqa_train_steps_per_epoch` denotes number of steps used for training CFNet on TVQA per epoch; `--imdb_train_steps_per_epoch` denotes number of steps used for training CFNet on IMDB per epoch; `--lr_tvqa_train` denotes initial learning rate used when training CFNet on TVQA; `--lr_imdb_train` denotes initial learning rate used when training CFNet on IMDB.
## Evaluation
To evaluate trained model checkpoint (e.g., `/path/to/output/dir/model_best.pth`), run
cd scripts/tvqa/
python eval.py
/path/to/prepared/tvqa
/path/to/output/dir/model_best.pth
val
cfnet
cfnet_auxiliary
/path/to/output/dir/eval_result.json
where `/path/to/prepared/tvqa` denotes directory storing prepared TVQA dataset; `/path/to/output/dir/model_best.pth` denotes path storing trained model checkpoint; `val` denotes split name used for evaluation; `cfnet` denotes model name used when training; `cfnet_auxiliary` denotes model name used when evaluating; `/path/to/output/dir/eval_result.json` denotes path storing evaluation result.
