Interpretable bilinear attention network with domain adaptation improves drug-target prediction | Paper

Open In Colab DOI:10.1038/s42256-022-00605-1 GitHub license

Introduction

This repository contains the PyTorch implementation of DrugBAN framework, as described in our Nature Machine Intelligence paper "Interpretable bilinear attention network with domain adaptation improves drug–target prediction". DrugBAN is a deep bilinear attention network (BAN) framework with adversarial domain adaptation to explicitly learn pair-wise local interactions between drugs and targets, and adapt on out-of-distribution data. It works on two-dimensional (2D) drug molecular graphs and target protein sequences to perform prediction.

Framework

DrugBAN

System Requirements

The source code developed in Python 3.8 using PyTorch 1.7.1. The required python dependencies are given below. DrugBAN is supported for any standard computer and operating system (Windows/macOS/Linux) with enough RAM to run. There is no additional non-standard hardware requirements.

torch>=1.7.1
dgl>=0.7.1
dgllife>=0.2.8
numpy>=1.20.2
scikit-learn>=0.24.2
pandas>=1.2.4
prettytable>=2.2.1
rdkit~=2021.03.2
yacs~=0.1.8
comet-ml~=3.23.1 # optional

Installation Guide

Clone this Github repo and set up a new conda environment. It normally takes about 10 minutes to install on a normal desktop computer.

# create a new conda environment
$ conda create --name drugban python=3.8
$ conda activate drugban

# install requried python dependencies
$ conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cudatoolkit=10.2 -c pytorch
$ conda install -c dglteam dgl-cuda10.2==0.7.1
$ conda install -c conda-forge rdkit==2021.03.2
$ pip install dgllife==0.2.8
$ pip install -U scikit-learn
$ pip install yacs
$ pip install prettytable

# clone the source code of DrugBAN
$ git clone https://github.com/pz-white/DrugBAN.git
$ cd DrugBAN

Datasets

The datasets folder contains all experimental data used in DrugBAN: BindingDB [1], BioSNAP [2] and Human [3]. In datasets/bindingdb and datasets/biosnap folders, we have full data with two random and clustering-based splits for both in-domain and cross-domain experiments. In datasets/human folder, there is full data with random split for the in-domain experiment, and with cold split to alleviate ligand bias.

Demo

We provide DrugBAN running demo through a cloud Jupyter notebook on Open In Colab. Note it is based on a small sample dataset of bindingdb due to the resource limitation of a free colab account. This demo only takes 3 minutes to complete the training and testing process. For running DrugBAN on the full dataset, we advise GPU ram >= 8GB and CPU ram >= 16GB.

The expected output and run time of demo has been provided in the colab notebook for verification.

Run DrugBAN on Our Data to Reproduce Results

To train DrugBAN, where we provide the basic configurations for all hyperparameters in config.py. For different in-domain and cross-domain tasks, the customized task configurations can be found in respective configs/*.yaml files.

For the in-domain experiments with vanilla DrugBAN, you can directly run the following command. ${dataset} could either be bindingdb, biosnap and human. ${split_task} could be random and cold.

$ python main.py --cfg "configs/DrugBAN.yaml" --data ${dataset} --split ${split_task}

For the cross-domain experiments with vanilla DrugBAN, you can directly run the following command. ${dataset} could beither bindingdb, biosnap.

$ python main.py --cfg "configs/DrugBAN_Non_DA.yaml" --data ${dataset} --split "cluster"

For the cross-domain experiments with CDAN DrugBAN, you can directly run the following command. ${dataset} could beither bindingdb, biosnap.

$ python main.py --cfg "configs/DrugBAN_DA.yaml" --data ${dataset} --split "cluster"

Comet ML

Comet ML is an online machine learning experimentation platform, which help researchers to track and monitor their ML experiments. We provide Comet ML support to easily monitor training process in our code. This is optional to use. If you want to apply, please follow:

  • Sign up Comet account and install its package using pip3 install comet_ml.

  • Save your generated API key into .comet.config in your home directory, which can be found in your account setting. The saved file format is as follows:

[comet]
api_key=YOUR-API-KEY
  • Set _C.COMET.USE to True and change _C.COMET.WORKSPACE in config.py into the one that you created on Comet.

For more details, please refer the official documentation.
