PROBLEM TO BE SOLVED: To realize high-speed pattern recognition and pattern recognition robust against noise to be superposed to an input pattern at random by using a database in which vectors generated from learning signals are simply stored for recognition without performing complicated calculation for the preparation of a learning pattern and without applying specific pre-processing to an input signal. SOLUTION: The pattern recognition device is constituted of a signal input part 11, a book information storage part 13, a vector generation part 15, a vector compression part 16, a class information generation part 17, a vector storage part 18, an index generation part 19, a vector search part 21, a class identification part 22, a class temporary storage part 24, and an identified result display device 23. Switches 1-8 are turned on/off in previously determined order. COPYRIGHT: (C)2005,JPO&NCIPI
