Method and apparatus for classifying patterns by use of neural network
 A method of and an apparatus for classifying an input pattern as a classification object by use of a neural network and transforming the input pattern into an output pattern as a result of classification, wherein there is obtained from the neural network having received an input pattern an output pattern for the input pattern such that the obtained output pattern is compared with a correct output pattern thereafter attained for the input pattern, a result of the comparison is sequentially stored in a memory, and the stored result of comparison is monitored to thereby detect an abnormality thereof.
