This repository contains the official code of the paper Efficient Subgraph GNNs by Learning Effective Selection Policies (ICLR 2024).

To perform hyperparameter tuning, make use of wandb:

1. In the yaml-files folder, choose the yaml file corresponding to the dataset of interest, say <config-name>. This file contains the hyperparameters grid.

2. Run

   wandb sweep yaml-files/<config-name>

   to obtain a sweep id <sweep-id>

3. Run the hyperparameter tuning with

   wandb agent <sweep-id>

   You can run the above command multiple times on each machine you would like to contribute to the grid-search

4. Open your project in your wandb account on the browser to see the results:

   • Compute mean and std of best val, test metric @ best val by grouping over all hyperparameters and averaging over the different seeds. Then, take the results corresponding to the configuration obtaining the best validation metric.
