    摘要: Processing data which belong to different classes and label data indicating the classes to which the processing data belong are input (S20). A distance relationship between the processing data is calculated (S22). An interclass separation degree between the classes is set (S23). The distance relationship is updated based on the label data and the interclass separation degree (S24). A data mapping relationship which approximates the updated distance relationship is calculated (S25).

    摘要: A plurality of pieces of learning data, each associated with a class to which the piece of the learning data belong, are input. In each piece of the learning data, a statistical amount of attribute values of elements in each of specific k parts, k being equal to or larger than 1, is calculated. Each piece of the learning data is mapped in a k-dimensional feature space as a vector having the calculated k statistics amounts as elements. Based on each piece of the mapped learning data and the classes to which the pieces of learning data belong, parameters for classifying input data into one of the plurality of classes are learned in the k-dimensional feature space. By using the parameters, pattern classification can be performed with high speed and high accuracy.

    摘要: A hierarchical processing apparatus includes a data input unit for time-sequentially inputting pattern data in a particular hierarchical level, a calculation parameter control data memory for storing calculation parameter control data, a local area recognition module for detecting a particular feature from pattern data, using the calculation parameter control data, and an intermediate result storage module for storing an intermediate result output from the local area recognition module. Depending on the hierarchical level of processing, a flow of data is controlled such that an input acquired via the data input unit or an intermediate result fed back from the intermediate result storage module and calculation parameter control data read from the calculation parameter control data memory are supplied to the local area recognition module. The hierarchical processing apparatus can perform various kinds of complicated calculations using a simple small-scale circuit with low power consumption.
