HIGH ACCURACY CLASSIFICATION METHOD AND SYSTEM FOR ENORMOUS VOLUME OF DATA DESCRIBED WITH MULTIPLE VARIABLES

摘要

A method and a device for classifying information which can be expressed withmultivariable by using a computer with high precision at high speed inaccordance with similarity, a method for permitting a computer to practice aprocedure for classifying infotmation which can be expressed withmultivariables with high precision at high speed in accordance withsimilarity, a program for executing the method, and a computer-readablerecorded medium on which the program is recorded. For example, the method forclassifying data on input vectors with high precision by a computer bynonlinear mappimg includes the following steps ((a) - (f)) (a) Input vectordata is inputted to a computer, (b) an initial neuron vector is set, (c) theinput vectors are classified into respective neuron vectors, (d) the neuronvectors are updated into structures similar to the structures of the inputvectors classified into the respective neuron vectors and the structures ofthe input vectors classified into the neighborhoods of the neuron vectors, (e)the steps ((c), (d)) are repeated until a predetermined learning times isreached, and (f) the input vectors are classified into the neuron vectors andoutputted.
