Learning Conditioned Graph Structures for Interpretable Visual Question Answering

This code provides a pytorch implementation of our graph learning method for Visual Question Answering as described in Learning Conditioned Graph Structures for Interpretable Visual Question Answering

Requirements

Data

To download and unzip the required datasets, change to the data folder and run

$ cd data; python download_data.py

To preprocess the image data and text data the following commands can be executed respectively. (Setting the data variable to trainval or test for preprocess_image.py and train, val or test for preprocess_text.py depending on which dataset you want to preprocess)

$ python preprocess_image.py --data trainval; python preprocess_text.py --data train

Pretrained model

If you would like a pretrained model, one can be found here: example model. This model achieved 66.2% accuracy on test.

Training

To train a model on the train set with our default parameters run

$ python run.py --train

and to train a model on the train and validation set for evaluation on the test set run

$ python run.py --trainval

Models can be validated via

$ python run.py --eval --model_path path_to_your_model

and a json of results from the test set can be produced with

$ python run.py --test --model_path path_to_your_model

To reproduce our results train a model on the trainval set with the default parameters, run the test script and evaluate the json on the EvalAI website.
