SINET

• This repository reproduces the experimental results of a paper "Causal Effect Estimation on Hierarchical Spatial Graph Data" presented in KDD 2023.

• https://dl.acm.org/doi/10.1145/3580305.3599269

• An example of hierarchical spatial graph data with global and local graphs containing covariates (blue), intervention (green).

• An example of network structures of SINet

Requirements

• python 3
• To install requirements:

conda env create -f environment.yml
conda activate sinet_env

Preprocessing

• The simulation data can be download from here and should be set in the folder ./data/.

Main analysis

• see demo_sinet.py for run a demo.
• see ./config/run_script.sh for commands for running scripts.
• Further details are documented within the code.
