Paper Title
Improvement Of Self-Organizing Maps Algorithm With Weighting Optimization

Abstract
The Self-Organizing Map (SOM) is a neural network algorithm based on unsupervised learning. It used for high dimensional data visualization. In other words, this algorithm maps high dimensional data to low dimensions space. Weight initializing is one of the main steps in SOM algorithm, because the proper initializing the weights has great influence on final convergence of network and it guides convergence toward local or global minimum. In order to reduce the iteration number and increase the rate of algorithm, we have decided to improve the initializing step of weights. For this purpose, weight initializing phase spilt to two steps and as observed from results, iteration no. decreased significantly. Keywords- Clustering, Self-Organizing Maps, Weighting Optimization.
