CST-GL

This is a PyTorch implementation of the paper: Correlation-aware Spatial-Temporal Graph Learning for Multivariate Time-series Anomaly Detection (TNNLS).

Requirements

The model is implemented using Python3.7 with dependencies specified in requirements.txt

Data Preparation

Water Treatment datasets

Follow the instruction in https://itrust.sutd.edu.sg/ to download SWaT and WADI datasets. Following Deng & Hooi (2021), we pre-process and downsample the original dataset. See the jupyter notebook in generate_data folder.

Server Machine datasets

Download the SMD dataset from https://github.com/zhhlee/InterFusion. Pre-process and place it to the data folder. Refer to generate_data foler.

Anomaly Detection
