TIME SERIES PATTERN EXTRACTION DEVICE, TIME SERIES PATTERN EXTRACTION METHOD AND TIME SERIES PATTERN EXTRACTION PROGRAM

摘要

PROBLEM TO BE SOLVED: To allow a gap of a time frame to enable extraction of a pattern, for time series data in which features intermittently appear.;SOLUTION: A time series pattern extraction device 10 creates a matrix in which time series data is sectioned by a predetermined time frame, from the time series data in which non-negative value vectors with non-negative value data as an element are aligned in a time series order; and with sets of the predetermined number of time frames acquired by shifting to an arbitrary set time interval, among time frames in the created matrix, extracts a pattern appearing between the sets of time frames.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2016,JPO&INPIT
