EVENT DETECTION AND CHARACTERIZATION IN BIG DATA STREAMS

摘要

Methods, systems, and apparatus, including computing device programs encoded on computing device storage media, for characterizing events in a data stream. In one of the methods a General Method, is used to construct a Specific Method, which performs the characterization of behavioral types of a particular system or set of systems. The Specific Method includes event extraction, dimensional reduction, and signature identification in the reduced dimensional space that map the events of a specific system into behavioral types.
