Title:
MEASUREMENT SIGNAL PROCESSING DEVICE, MEASUREMENT SIGNAL PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/206076
Kind Code:
A1
Abstract:
In the present invention, a model learning unit defines, for each learning set that contains a measurement signal and at least one type of prescribed characteristic value indicative of a characteristic of the measurement signal as a target value, a model parameter used to calculate an estimate value obtained by performing a calculation on the measurement signal using a prescribed mathematical model so that the difference between the estimate value and the target value becomes small, defines a characteristic value set, which is a set of multiple types of characteristic values indicative of characteristics of the measurement signal including the target value, such that each type of the target value becomes common between a plurality of characteristic value sets, and generates, for each of the characteristic sets, the learning set that contains the target value and a measurement signal having the characteristics represented by the aforementioned multiple types of characteristic values.
