GDN

Code implementation for : Graph Neural Network-Based Anomaly Detection in Multivariate Time Series(AAAI'21)

Installation

Requirements

Install packages

    # run after installing correct Pytorch package
    bash install.sh

Quick Start

Run to check if the environment is ready

    bash run.sh cpu msl
    # or with gpu
    bash run.sh <gpu_id> msl    # e.g. bash run.sh 1 msl

Usage

We use part of msl dataset(refer to telemanom) as demo example.

Data Preparation

# put your dataset under data/ directory with the same structure shown in the data/msl/

data
 |-msl
 | |-list.txt    # the feature names, one feature per line
 | |-train.csv   # training data
 | |-test.csv    # test data
 |-your_dataset
 | |-list.txt
 | |-train.csv
 | |-test.csv
 | ...

Notices:

  • The first column in .csv will be regarded as index column.
  • The column sequence in .csv don't need to match the sequence in list.txt, we will rearrange the data columns according to the sequence in list.txt.
  • test.csv should have a column named "attack" which contains ground truth label(0/1) of being attacked or not(0: normal, 1: attacked)

Run

    # using gpu
    bash run.sh <gpu_id> <dataset>

    # or using cpu
    bash run.sh cpu <dataset>

You can change running parameters in the run.sh.

Others

SWaT and WADI datasets can be requested from iTrust
