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.
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.
AEDetector detects anomaly based on the reconstruction error of an autoencoder network.
DBScanDetector uses DBSCAN clustering algortihm for anomaly detection.
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
