FEATURE QUANTITY CONVERSION APPARATUS, LEARNING DEVICE, RECOGNITION DEVICE, AND FEATURE QUANTITY CONVERSION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a feature quantity conversion apparatus which performs nonlinear transform on a feature quantity at a high speed.SOLUTION: A feature quantity conversion apparatus 10 includes: bit rearrangement units 111-11N for generating rearranged bit strings by rearranging input binary feature vector elements in different arrangements; logical operation units 121-12N for performing logical operation between each of the rearranged bit strings and the input feature vectors to generate logical operation bit strings; and a feature integration unit 13 which integrates the generated logical operation bit strings to generate a nonlinear transform feature vector.
