Pattern classification system
First Claim
1. A pattern classification system comprising:
- a plurality of classification sections each including;
means for storing information of N coefficients W representing a reference pattern,means for calculating an evaluation value V on the basis of N input signals S and the N coefficients W, the N input signals representing an input pattern, the evaluation value V representing a relation between the input pattern and the reference pattern,means for storing information of a fixed threshold value R,means for comparing the evaluation value V and the threshold value R and for outputting a first part of an estimation signal depending on a result of the comparing, the estimation signal first part including a category signal P which represents a category;
means for storing a counter signal C, representing a frequency in use of the classification section, andmeans for outputting the stored counter signal as a second part of the estimation signal in response to the result of the comparing the evaluation value V and threshold value R;
a selection section for selecting one of a plurality of categories represented by the category signals P outputted from the classification sections in response to the counter signals outputted from the classification sections and for outputting a signal Px representing the selected one of the categories; and
an adjustment section for adjusting parameters in the classification sections in response to the output signal Px of the selection section and a teacher signal T representing a target state of the output signal Px of the selection section, the parameters including the coefficients W.

Abstract
A pattern classification system includes a plurality of classification sections. Each of the classification sections includes a device for storing information of N coefficients W representing a reference pattern, a device for calculating an evaluation value V on the basis of N input signals S and the N coefficients W, the N input signals representing an input pattern, the evaluation value V representing a relation between the input pattern and the reference pattern, a device for storing information of a fixed threshold value R, and a device for comparing the evaluation value V and the threshold value R and for outputting an estimation signal depending on a result of the comparing, the estimation signal including a category signal P which represents a category. A selection section is operative for selecting one of categories in response to the category signals outputted from the classification sections and for outputting a signal Px representing the selected one of the categories. An adjustment section is operative for adjusting parameters in the classification sections in response to the output signal Px of the selection section and a teacher signal T, the parameters including the coefficients W.
