FARSI HANDWRITING RECOGNITION WITH MIXTURE OF RBF EXPERTS BASED ON PARTICLE SWARM OPTIMIZATION

Abstract:
In this paper, a classifiers combination based on Particle Swarm Optimization (PSO) is presented for Farsi handwritten digit recognition. This model consists of four Radial Basis Function (RBF) neural networks as experts and another as the gating network which tries to separate the input space among the experts. PSO is used to train RBF neural networks (NNs). Input data is an 81-element vector. This vector is extracted using loci characterization method. It is shown that recognition rate of the proposed method is 97.1% which is 1.8% more than the rate of mixture of RBF experts previously ran on the same dataset. |
