Abstract
It is now well known that most of the problems are classificatory in nature eg Face Recognition, Speaker Recognition, Word Recognition, etc. In this paper we propose a new model for these classificatory problems. This model is based on the Grammatical Evolution of the Genetic Algorithms. The model that we propose here is a type of fuzzy logic inference system model. Rules are in form of a collection of points representing every class. The separation between the unknown input and these representative points determine the degree of belongingness of the unknown input to the specific class being considered. Multiple contributions from same classes are simply added together. The training data set is used for the purpose of generating the initial set of configurations of this fuzzy model. The fuzzy functions are parameterized by adding fuzzy parameters, like any neuro-fuzzy model. These parameters are trained by a valedictory data set using a training algorithm. The performance of the system over the training and valedictory data set serve as the fitness function. Variable mutation rate is applied. We tested the effectiveness of the algorithm over the picture learning problem and received better results than any of the present algorithms.
