DEVICE, METHOD AND PROGRAM FOR AUTHENTICATION

摘要

PROBLEM TO BE SOLVED: To improve the accuracy of a pattern matching utilizing neural network. SOLUTION: In registering a new authentication category on the basis of new data for registration, a new neural network corresponding to the new category is generated and arranged parallelly with a registered neural network. An effective point selecting part 13 selects a statistically stable point whose separation distance from patterns of the other registered neural network as an effective point from a plurality of data candidate groups for registration during a process for registering a data distribution state of the new category in a template for neural network selection. A neural network registering and selecting part selects and drives a neural network corresponding to input data, compares output results and outputs authentication results.
