Abstract—A recent practical research reported that a layered
neural network when applies pattern coding, which is a method
to convert analogue input value into a multidimensional binary
pattern, has a high capability of pattern classification. However,
it does not conduct sufficient basic analysis; thus, the effect of
pattern coding is unclear. The present study examines the
effectiveness of pattern coding in pattern classification.
Numerical experiments on two-dimensional two-class
classification problems show that a multilayer perceptron can
learn complex decision boundaries when pattern coding is
applied. The results also indicate that pattern coding is also
effective for a simple perceptron if selective desensitization is
applied jointly.
