What is Anomaly Detector?

Important

Starting on the 20th of September, 2023 you won’t be able to create new Anomaly Detector resources. The Anomaly Detector service is being retired on the 1st of October, 2026.

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 machine learning (ML) knowledge, either batch validation or real-time inference.

This documentation contains the following types of articles:

  • Quickstarts are step-by-step instructions that let you make calls to the service and get results in a short period of time.
  • How-to guides contain instructions for using the service in more specific or customized ways.
  • Tutorials are longer guides that show you how to use this service as a component in broader business solutions.
  • Code samples demonstrate how to use Anomaly Detector.
  • Conceptual articles provide in-depth explanations of the service's functionality and features.

Anomaly Detector capabilities

With the Anomaly Detector, you can detect anomalies in one variable using Univariate Anomaly Detector.

Feature Description
Univariate Anomaly Detection Detect anomalies in one variable, like revenue, cost, etc. The model was selected automatically based on your data pattern.

Univariate Anomaly Detection

The Univariate Anomaly Detector API enables you to monitor and detect abnormalities in your time series data without having to know machine learning. The algorithms adapt by automatically identifying and applying the best-fitting models to your data, regardless of industry, scenario, or data volume. Using your time series data, the API determines boundaries for anomaly detection, expected values, and which data points are anomalies.

Using the Anomaly Detector doesn't require any prior experience in machine learning, and the REST API enables you to easily integrate the service into your applications and processes.

With the Univariate Anomaly Detector, you can automatically detect anomalies throughout your time series data, or as they occur in real-time.

Feature Description
Streaming detection Detect anomalies in your streaming data by using previously seen data points to determine if your latest one is an anomaly. This operation generates a model using the data points you send, and determines if the target point is an anomaly. By calling the API with each new data point you generate, you can monitor your data as it's created.
Batch detection Use your time series to detect any anomalies that might exist throughout your data. This operation generates a model using your entire time series data, with each point analyzed with the same model.
Change points detection Use your time series to detect any trend change points that exist in your data. This operation generates a model using your entire time series data, with each point analyzed with the same model.
