Installation

Lua setup

The main modeling code is written in Lua using torch Installation instructions are located here

After installing torch, install / update these packages by running the following:

luarocks install torch
luarocks install nn
luarocks install optim

CUDA support (Optional)

To enable GPU acceleration with CUDA, you'll need to install CUDA 6.5 or higher as well as cutorch and cunn. You can install / update the torch CUDA libraries by running:

luarocks install cutorch
luarocks install cunn

LFS

Install git large file storage (LFS) in order to download the dataset directly from this git repository.

R: https://www.r-project.org/

Usage

Step 1: Get the Data

tar xvzf data/deepbind.tar.gz -C data/

Step 2: Train the model

You can train one of the 3 types of models (CNN, RNN, or CNN-RNN). Check the flags in main.lua for parameters to run the code.

For CNN model:

th main.lua -cnn

For CNN model:

th main.lua -rnn

For CNN-RNN model:

th main.lua -cnn -rnn

Step 3: Visualize the Model's Predictions

Once you have trained models, you can visualize the predictions.
