Title:
MANAGEMENT SYSTEM AND MACHINE LEARNING DEVICE THEREFOR AND MANAGING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/161835
Kind Code:
A1
Abstract:
The present invention creates a cause-and-effect diagram on the basis of expert knowledge about association between an item to be managed and a plurality of causes. In the cause-and-effect diagram, the plurality of causes are data acquired in the field of manufacture or service in which the item to be managed is set, and the degree of importance for the item to be managed is imparted to each of the plurality of causes. In machine learning, first, a link structure for a probability model is set on the basis of the relationship between the item to be managed and the plurality of causes in the cause-and-effect diagram, and a value for each node of the probability model is set on the basis of the degree of importance imparted to each of the plurality of causes. Then, the link structure or the value for each node is learned using the data acquired in the field of manufacture or service.
