Installation

Install PyTorch following the instuctions on the [official website] (https://pytorch.org/). The code has been tested over PyTorch 0.4.1 and 1.0.0 versions.

Then install the other dependencies.

pip install -r requirements.txt

Test run

Unzip the dataset file

unzip dataset.zip

and run

python main.py

Default parameters are not the best performing-hyper-parameters. Hyper-parameters need to be specified through the commandline arguments. Please refer to our paper for the details of how we set the hyper-parameters.

Type

python main.py --help

to learn hyper-parameters to be specified.
