Anomaly Detector v1.1

Anomaly Detector is an AI service with a set of APIs, which enables you to monitor and detect anomalies in your time series data with little ML knowledge, either batch validation or real-time inference. It includes the following features:

  • Univariate Anomaly Detection - Detect different types of anomalies in single variable.
  • Multivariate Anomaly Detection - Detect different types of anomalies in multiple variables from your equipment or system.

Multivariate Anomaly Detection - List Multivariate Models
