This repository provides the source code for the AISTATS'22 paper Structured Multi-task Learning for Molecular Property Prediction, with the following contributions:

1. To our best knowledge, we are the first to propose a new research problem: multi-task learning with an explicit task relation graph;
2. We construct a domain-specific multi-task dataset with relation graph for drug discovery;
3. We propose state graph neural network-energy based model (SGNN-EBM) for task structured modeling in both the latent and output space.

In the future, we will merge it into the TorchDrug package.

Baselines

For implementation, this repository also provides the following multi-task learning baselines:

• standard single-task learning (STL)
• standard multi-task learning (MTL)
• Uncertainty Weighing (UW)
• GradNorm
• Dynamic Weight Average (DWA)
• Loss-Balanced Task Weighting (LBTW)

Dataset

In this work, we propose a novel dataset with explicit task relation. Basically it is a molecule property task dataset, where the task refers to a binary classification problem on a ChEMBL assay. Each task measures certain biological effects of molecules, e.g., toxicity, inhibition or activation of proteins or whole cellular processes, etc. We focus on tasks that target at proteins. Then we extract the task relation by aggregating the protein-protein interaction (PPI, like String dataset) accordingly.

For the detailed pre-processing steps, please check this instruction. The pre-processed datasets can be downloaded here.

Structured Multi-Task Learning: SGNN-EBM

Evaluation on the pre-trained models

We also provide the pre-trained model weights and evaluation scripts accordingly. First you can download the checkpoints here. All the optimal hyper-parameters are provided in the bash scripts.

cd checkpoint

bash eval_SGNN.sh > eval_SGNN.out
bash eval_SGNN_EBM.sh > eval_SGNN_EBM.out

Training from scratch

Here we provide the script for training the SGNN and SGNN-EBM (adaptive with pre-trained SGNN). Note that the pre-trained SGNN models is required (either using last script or from the pre-trained weights).

bash submit_SGNN.sh
bash submit_SGNN_EBM.sh

Baselines

We also provide the scripts for all six STL and MTL baselines under the scripts folder.

sgnn-ebm's Issues

Help for checkpoint

Hello, there are only posters and slides in the given connection, I would like to ask where I can download the pre-trained checkpoint.

Application for regression tasks

Hello! Is there a way to train a model for multi-task regression? And will it be desirable to do so with SGNN-EBM?

I'd like to train a property predictor that predicts two or so properties for molecules, where those properties are presumably highly correlated, considering their similar physics.

I'd be grateful to have some advice about the two questions.
