EVENT DETECTION APPARATUS AND EVENT DETECTION METHOD

摘要

An event detection apparatus determines the occurrence of an abnormal event based on input data without predefining and learning normal or abnormal patterns. A first data obtaining unit obtains first data. A feature quantity classifying unit obtains a feature quantity corresponding to the first data, generates a plurality of clusters for classifying the obtained feature quantity, and classifies the feature quantity into a corresponding one of the clusters. A learning unit learns a plurality of identifiers using feature quantities classified into the clusters. A second data obtaining unit obtains second data. An identifier unit inputs a feature quantity corresponding to the second data into the plurality of learned identifiers, and receives an identification result from each identifier. A determination unit determines whether the second data includes an identification target event based on the obtained identification result.

1. An event detection apparatus, comprising:
a first data obtaining unit configured to obtain first data; a plurality of identifiers; a feature quantity classifying unit configured to obtain a feature quantity corresponding to the first data, generate a plurality of clusters for classifying the obtained feature quantity, and classify the feature quantity into a corresponding one of the clusters; a learning unit configured to learn the plurality of identifiers using feature quantifies classified into the clusters; a second data obtaining unit configured to obtain second data; an identifier unit configured to input a feature quantity corresponding to the second data into the plurality of learned identifiers, and receive an identification result from each identifier; and a determination unit configured to determine whether the second data includes an identification target event based on the obtained identification result.
