Abstract
A pattern recognition device is arranged to have learning of a reference pattern vector carried out in a recognition unit by making use of the pause periods in the recognition processing, without particularly providing a learning section for learning the reference pattern vector. Namely, a part or the entirety of the arithmetic processing unit where the recognition result is obtained in the recognition unit by collating the input pattern with the recognition dictionary, can be utilized as the learning portion of the reference pattern vector. In concrete terms, the operation of multiplication-accumulation (inner product) which represents the main operation in the recognition processing and the learning processing, can be carried out by means of similar processes of handling. Therefore, by utilizing the processing section for sum of the products operation, of the recognition unit, which is in the idle state for pattern recognition, it becomes possible to carry out learning the reference pattern vector efficiently in time, without forcibly interrupting the pattern recognition processing by formally setting a learning condition.
