Question

Which machine learning technique can be used for anomaly detection?

Options

AA machine learning technique that classifies objects based on user supplied images.
BA machine learning technique that understands written and spoken language.
CA machine learning technique that classifies images based on their contents.
DA machine learning technique that analyzes data over time and identifies unusual changes.

Explanation

Anomaly Detector, an AI service that helps you foresee problems before they occur. Easily embed time-series anomaly detection capabilities into your apps to help users identify problems quickly. Anomaly Detector ingests time-series data of all types and selects the best anomaly detection algorithm for your data to ensure high accuracy. Detect spikes, dips, deviations from cyclic patterns, and trend changes through both univariate and multivariate APIs. Customize the service to detect any level of anomaly. Deploy the anomaly detection service where you need it - in the cloud or at the intelligent edge.
