Anomaly Detection Toolkit (ADTK)

Build Status Documentation Status Coverage Status PyPI Downloads Code style: black Binder

Anomaly Detection Toolkit (ADTK) is a Python package for unsupervised / rule-based time series anomaly detection.

As the nature of anomaly varies over different cases, a model may not work universally for all anomaly detection problems. Choosing and combining detection algorithms (detectors), feature engineering methods (transformers), and ensemble methods (aggregators) properly is the key to build an effective anomaly detection model.

This package offers a set of common detectors, transformers and aggregators with unified APIs, as well as pipe classes that connect them together into models. It also provides some functions to process and visualize time series and anomaly events.

See for complete documentation.


Prerequisites: Python 3.5 or later.

It is recommended to install the most recent stable release of ADTK from PyPI.

pip install adtk

Alternatively, you could install from source code. This will give you the latest, but unstable, version of ADTK.

git clone
cd adtk/
git checkout develop
pip install ./


Please see Quick Start for a simple example.

For more detailed examples of each module of ADTK, please refer to Examples section in the documentation or an interactive demo notebook.
