ABSTRACT:
An orthogonalizing time filter section is arranged in place of a Gram Schmidt orthogonalizing section. The orthogonalizing time filter section is constituted by a plurality of filters for performing smoothing processing and differential processing. The orthogonalizing time filter section obtains an average pattern of acquired learning patterns, and smoothes the average pattern along the time base to obtain a dictionary of a first axis. The section differentiates the average pattern along the time base to obtain a dictionary of a second axis. The above processing is repeated for each category, thus generating an orthogonalized dictionary.
