INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND RECORDING MEDIUM FOR CLASSIFYING INPUT DATA

摘要

A holding unit of an information processing apparatus holds a classification model and characteristic information for each of a plurality of groups acquired by dividing a plurality of feature values extracted from a plurality of training data pieces belonging to a specific class. Then, a feature extraction unit extracts a feature value from input data, and a selection unit selects one or more group(s) from the plurality of groups based on this extracted feature value and the characteristic information held by the holding unit. Then, a determination unit determines whether the input data belongs to the specific class with use of the classification model(s) corresponding to the selected group(s).
