LEARNING METHOD, ESTIMATION METHOD, LEARNING DEVICE, ESTIMATION DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/259393
Kind Code:
A1
Abstract:
This learning device generates a first trained model by training a learning model, which is for outputting an explained variable upon the input of an explanatory variable, on the basis of first training data representing a pair of a first explanatory variable for training and a first explained variable for training, such that a correlation coefficient between the first explained variable for training and an explained variable output from the learning model is maximized during the training of the learning model. In addition, the learning device generates a second trained model by re-training the first trained model on the basis of second training data representing a pair of a second explanatory variable for training and a second explained variable for training, such that a discrepancy between the second explained variable for training and an explained variable output from the first trained model is minimized during the re-training of the first trained model.
