STIMULUS SAMPLING PATTERN RECOGNITION
Abstract
A generalized computer model was constructed to simulate the behavior of organisms according to various versions of stimulus sampling theory. Results already reported dealt with the learning behavior of rats in a T-maze. With the addition of new routines to specify the simulated environment of the simulated organism, a similar basic program has learned to discriminate among visual patterns consisting of carelessly hand-drawn al phabetic characters, each of which is presented in a number of variations. Input to the program is a binary representation of the presence or absence of parts of the figure in a 20 x 20 matrix superimposed on the figure to be recognized. Each cell of the matrix is treated as a separate stimulus having various numbers of elements as sociated with all the responses that can be made. A random sample of elements from stimuli present in the visual field is used to determine the response any trial. When a correct response is made, all elements sampled on that trial become associated with that response. Changes in learning rates occur as the probability of selecting available stimulus elements is changed.
