Title:
DATA PREDICTION DEVICE, DATA PREDICTION METHOD, AND DATA PREDICTION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/184561
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce the quantity of data used to calculate regression coefficients, reduce the bandwidth for collecting and transmitting data, and reduce computation throughput in a learning process. A data prediction device according to the present disclosure includes: a data collection unit that transmits a collected plurality of data, and selected data that was selected from the plurality of data; a first regression coefficient computation unit that computes regression coefficients on the basis of the received plurality of data and using a first computation method for calculating regression coefficients by L1 regularization, and transmits selection information for selecting data corresponding to regression coefficients among the calculated regression coefficients having an absolute value equal to or greater than a threshold value to the data collection unit; a second regression coefficient computation unit that computes regression coefficients on the basis of the received selected data and using a second computation method different from the first computation method; and a prediction unit that outputs a prediction result that was predicted on the basis of the received selected data and the regression coefficients computed by the second regression coefficient computation unit.
