This repository is the official implementation of Robust Graph Representation Learning for Local Corruption Recovery.

Requirements

To install requirements:

pip3 install -r requirements.txt

Folder-generate_noisedata

The folder generate_noisedata contains two types of noise, i.e. injecttion noise and noise by mettack. Also, the gae_run.py runs graph auto encoder to find the noisy item after the nosie generated on the feature matrix.

Folder-denoise

Run the main_denoise.py will use the regularized optimization method to denoise the local corrupted featue matrix.

Folder-class

Run the graph_class.py will test the performance on the denoised dataset.

All Experiments

After sepecify the noise type and create noise on feature matrix, you can use the following command

sh run_all.sh

to run graph auto encoder, denosing and classification tasks.
