Title:
REGRESSION ANALYSIS SYSTEM AND REGRESSION ANALYSIS METHOD THAT PERFORM DISCRIMINATION AND REGRESSION SIMULTANEOUSLY
Document Type and Number:
WIPO Patent Application WO/2013/077093
Kind Code:
A1
Abstract:
The invention addresses the problem of: solving a problem in which a case not enabling computation of a regression estimate value occurs depending on a discrimination result attained by applying a regression method after a discrimination method; and precisely finding an estimation formula even when a sample set for which to apply the regression method is small. An estimation formula that simultaneously satisfies regression and discrimination is obtained by: compositing a discrimination evaluation function that evaluates discrimination precision with a regression evaluation function that evaluates regression precision; computing a composite evaluation function; and optimizing the composite evaluation function.
