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.
