Study model creation program, image identification information grant program and study model creation device and image identification information

摘要

PROBLEM TO BE SOLVED: To provide a learning model creation program capable of creating a learning model which can give identification information of higher reliability to an unknown image in comparison with a learning model created by using a binary discriminator and to provide a learning model identification information giving program, a learning model creation device, and an image identification information giving device.;SOLUTION: The learning model creation program makes a computer function as: creation means which extracts a plurality of feature quantities from a learning image being an image of which the identification information representing contents of the image is known, and classifies the plurality of feature quantities by using a binary discriminator and creates learning models for associating the identification information and the feature quantities with each other, per type of the identification information and the feature quantities; and optimizing means which approximates a formula for obtaining a conditional probability of the identification information, by a sigmoid function and optimizes the learning models per type of the identification information by optimizing parameters of the sigmoid function so as to maximize the conditional probability of the identification information.;COPYRIGHT: (C)2012,JPO&INPIT
