-
-Anomaly detection in Amazon OpenSearch Service automatically detects anomalies in your OpenSearch data in near-real time by using the Random Cut Forest (RCF) algorithm. RCF is an unsupervised machine learning algorithm that models a sketch of your incoming data stream. The algorithm computes an `anomaly grade` and `confidence score` value for each incoming data point. Anomaly detection uses these values to differentiate an anomaly from normal variations in your data. 
-
-To simplify the process of creating anomaly detectors, AI Assistant can generate suggested detectors based on your selected data source on the **Discover** page. AI Assistant supports suggested anomaly detectors for any language.
