Detecting-Multivariate-Time-Series-Anomalies-with-Zero-Known-Label

This repository provides a PyTorch implementation of MTGFlow (Paper), which is the unsupervised anomaly dection and localization method. This repository is based on GANF.

Data

We test our method for five public datasets, e.g., SWaT, WADI, PSM, MSL, and SMD.

SWaT WADI

mkdir Dataset
cd Dataset
mkdir input

Download the dataset in Data/input.

Train

train for MITGFlow For example, training for WADI

sh runners/run_WADI.sh

train for DeepSVDD, DeepSAD, DROCC, and ALOCC.

python3 train_other_model.py --name SWaT --model DeepSVDD

train for USAD and DAGMM We report the results by the implementations in the following links:

USAD and DAGMM

Test

We provide the pretained model of MTGFlow.

For example, testing for WADI

sh runners/run_WADI_test.sh
