ABSTRACT:
A discriminant or identification function is used for pattern recognition in which the highest performance can be offered when adaptation is made. Learning is carried out while a discriminant or identification function is adapted to a learning sample. For example, a standard pattern of the character "A" used as an identification function is learned such that when the character "A" slanting in the right or left direction is input, the standard pattern of the character "A" is rotated (adapted) in accordance with the slanting of the input learning sample.
