## Textual and Visual Features

Please download the following files and place them in the following dir structure:

$PATH_TO_DATASETS$/Context/
    $PATH_TO_DATASETS$/Drink_Bottle/

Refer to the path after the link to correctly place the file.

The visual features were extracted by the Faster R-CNN proposed by in the paper Bottom-Up and Top-Down Attention for Image Captioning and Visual Question Answering.

For more details, please refer to our paper pre-print.

## Train

$ export Data_DIR=$PATH_TO_DATASETS$
    
    
    $ python train.py (Please refer to the code to decide the args to train the model)

Example:

Context dataset

$python train.py context --batch_size 64 --model fullGCN_bboxes --ocr google_ocr --embedding fasttext --max_textual 15 --max_visual 36 --projection_layer mean --fusion concat --data_path $Data_DIR --split 1

Drink Bottle dataset

$python train.py bottles --batch_size 64 --model fullGCN_bboxes --ocr google_ocr --embedding fasttext --max_textual 15 --max_visual 36 --projection_layer mean --fusion concat --data_path $Data_DIR --split 1

## Test

Current Test.py file has a minor bug due to visualization experiments. To perform evaluation of the model, you can run the train.py file with the flag --test as True. Example:
