Title:
LEARNING DEVICE, ABNORMALITY DETECTION DEVICE, LEARNING METHOD, AND ABNORMALITY DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/214833
Kind Code:
A1
Abstract:
A learning device according to one embodiment is characterizing by having: an input unit for inputting a dataset of data that represents an aggregate composed of pairs of an attribute value and attribute information; a computation unit for calculating, using an aggregate of vectors which are a combination of the attribute value with an embedded vector in which the attribute information is embedded, a prediction value that corresponds to the attribute value of each piece of data included in the dataset; and a learning unit for updating parameters that include the embedded vectors so as to minimize a difference between the attribute value and the prediction value corresponding to the attribute value.
