Anomaly Detection
Anomaly Detection detects abnormal samples in a given time series. Chronos provides a set of unsupervised anomaly detectors.
View some examples notebooks for Datacenter AIOps.
1. ThresholdDetector
ThresholdDetector detects anomaly based on threshold. It can be used to detect anomaly on a given time series (notebook), or used together with Forecasters to detect anomaly on new coming samples (notebook).
View ThresholdDetector API Doc for more details.
2. AEDetector
AEDetector detects anomaly based on the reconstruction error of an autoencoder network.
View anomaly detection notebook and AEDetector API Doc for more details.
3. DBScanDetector
DBScanDetector uses DBSCAN clustering algortihm for anomaly detection.
.. note::
Users may install ``scikit-learn-intelex`` to accelerate this detector. Chronos will detect if ``scikit-learn-intelex`` is installed to decide if using it. More details please refer to: https://intel.github.io/scikit-learn-intelex/installation.html
