ABSTRACT:
With respect to pattern recognition or the like, this invention is aimed at reducing the arithmetic processing steps of determining analogy between an inputted pattern and reference patterns in order to enhance the speed of the recognition process. At first, a quantization code book is designed to prepare a single-output table and a mixture-output table. Then, referring to these tables, single-output data and mixture-output data are worked out from an inputted pattern. In accordance with these data thus worked out, the adaptability between the inputted pattern and reference patterns is calculated in order to obtain the analogy between them.
