Instructions for Reproducibility

1. In the generation directory, use the following command to download and preprocess datasets:

   source generate_graphs.sh

2. Once the datasets are downloaded and preprocessed, in the root directory, use the following command to train models and save results to the evaluation directory.

   source search.sh

3. After training the models and saving the results, load and visualize the results in the analysis_social_sgnn.ipynb or analysis_synthetic_sgnn.ipynb notebook located in the evaluation directory.
