K-Means is a clustering algorithm used for anomaly detection in time series data, as demonstrated by Anais Dotis-Georgiou's work with InfluxDB and Chronograf.` `She successfully applied K-Means to detect anomalies in EKG data using the InfluxDB Python Client Library, and utilized Chronograf to manage alerts and autogenerate a TICKscript for Kapacitor.` `This approach allows for efficient detection of unusual patterns in time series data, enabling better insights into system behavior and potential issues.
