摘要

PROBLEM TO BE SOLVED: To reduce the processing load of exponentiation calculation of kernel even when the number of elements of a feature vector increases.SOLUTION: Feature vectors are extracted from information for learning, and a classification plane allowing correct classification of the information for learning indicating how to classify is formed. As the kernel used for a nonlinear support vector machine used for forming the classification plane, a function expression of exponentiating the calculation value of the calculation of determining the similarity between the feature vectors is used. A plurality of classification planes are formed while the combination of a regularization parameter indicating the tolerance of false classification and an exponentiation parameter of the kernel is changed. Using the plurality of formed classification planes, information for a test indicating how to classify is classified, and a classification plane allowing the information for a test to be most accurately classified is selected and is set in an information classification device.SELECTED DRAWING: Figure 7
