Information processing device, data structure of correlation model, program, information processing method, and method of manufacturing data structure of correlation model

摘要

To provide an information processing device or the like that can estimate a tendency with a small amount of calculation. The information processing device (20) includes a first feature vector in which values associated with the plurality of first items are elements, and a second feature vector in which values associated with the plurality of second items are elements. A teacher data acquisition unit for acquiring a plurality of teacher data including a set, an element associated with the same first item in the plurality of first feature vectors acquired by the teacher data acquisition unit, and a plurality of the second A calculation unit that calculates each element of a correlation model matrix relating to a correlation between the first feature vector and the second feature vector based on an element associated with the same second item in the feature vector. Prepare.
