FEATURE QUANTITY EXTRACTION DEVICE, FEATURE QUANTITY EXTRACTION FUNCTION INFORMATION GENERATOR, AND METHOD AND PROGRAM THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a technique for calculating feature quantity using a feature quantity extraction function optimized to calculate proper feature quantity.SOLUTION: The feature quantity extraction device includes a feature quantity extraction part 11 which calculates a feature quantity of a piece of observation data by inputting the observation data to a feature quantity extraction function. The feature quantity extraction function is optimized according to an inclination method using an optimization index based on Neyman Pearson's criteria.SELECTED DRAWING: Figure 1
