Title:
LEARNING DEVICE, PREDICTION DEVICE, LEARNING METHOD, AND LEARNING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/064899
Kind Code:
A1
Abstract:
According to the present invention, a first learning unit (101) learns a differential model (111) for predicting the difference between current observation data at the current time and past observation data at each of a plurality of past times, the current observation data and the past observation data being observation data obtained by observing an observation target at a plurality of observation points at each time. A second learning unit (102) learns a (past) prediction model (112) for predicting a variation of the observation target by using the past observation data. A first generation unit (103) generates corrected past data obtained by correcting the difference between the past observation data and the current observation data by using the differential model (111). A third learning unit (104) learns a (current) prediction model (133) for predicting a variation of the observation target by using the current observation data, the differential model (111), the (past) prediction model (112), and the corrected past data. Accordingly, the variation of the observation target is suitably predicted, even when the variation of the observation target is abnormal.
