Title:
STATE PREDICTION DEVICE AND STATE PREDICTION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/163141
Kind Code:
A1
Abstract:
A state prediction device 100 is provided with: a learning data generation unit 212 for acquiring measurement data acquired in an observation sensor 300 at a predetermined time interval, performing sectioning for each operation mode of a subject to be observed, and generating learning data; a clustering unit 213 for classifying a predetermined number of pieces of learning data into predetermined categories, putting labels thereon, and generating supervised data; a learning unit 214 for inputting the supervised data to a learning algorism and learning the data, generating a learned model 252, and generating representative data of each category; a time-series model generation unit 215 for arranging labels 244 put on the learning data within a predetermined model generation unit period in an order in which the learning data is generated in a chronological order, and generating a time-series model 273; and a prediction unit 220 for calculating a prediction value by using the time-series model 273 from measurement data newly acquired.
