Event Detection
Event detection is the automated process of identifying and analyzing significant occurrences or patterns within data streams, time series, or real-world observations.
Overview
Event detection encompasses the methodologies and techniques used to automatically identify meaningful occurrences or patterns within various types of data. This critical component of data analysis systems enables the discovery of significant moments, changes, or anomalies that warrant attention or action.
