Title:
INFORMATION ANALYSIS DEVICE, INFORMATION ANALYSIS METHOD, AND INFORMATION ANALYSIS PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/053828
Kind Code:
A1
Abstract:
Provided is an information analysis device in which when a prediction target is represented by the sum of a plurality of partial prediction targets, a set generation unit 81 generates a set of groups by grouping partial prediction targets into a plurality of groups. A partial sum model generation unit 82 generates a learning model in which the sum of the partial prediction targets included in the groups serves as an objective variable. A prediction target calculation unit 83 calculates the value of the prediction target from predicted values for the groups calculated using the learning model. An evaluation unit 94 evaluates the set of groups on the basis of the difference between the calculated value of the prediction target and the actual value of the prediction target. A control unit 85 controls the set generation unit 81 so that said set generation unit 81 generates a set of groups having a different composition than a previously generated set of groups. The set generation unit 81 generates a set of groups in accordance with control by the control unit 85.
