Document Type and Number:
WIPO Patent Application WO/2019/012653
Kind Code:
A1
Abstract:
A learning system is provided with: a teacher data acquisition unit that acquires teacher data with which event types are associated in predetermined periods for each of a plurality of feature amounts obtained by converting time series data into each of the predetermined periods; and a classifier learning unit that uses a feature amount group including feature amounts corresponding to some or all of the periods among the plurality of feature amounts included in the teacher data to perform learning in a plurality of mutually different classifiers by changing the combinations of the feature amount group and repeatedly performing an operation in which learning is performed in a classifier for classifying the event types. The learning system is characterized in that the event types include a first event type corresponding to a state in which a target event that is to be classified is occurring and a second event type corresponding to a state in which the target event is not occurring.
