Abstract
Proposes an escape methodology to the local minima problem of self-organizing feature maps generated in the overlapping regions which are equidistant to the corresponding winners. Two new versions of the self-organizing feature map are derived equipped with such a methodology. The first approach introduces an excitation term, which increases the convergence speed and efficiency of the algorithm while increasing the probability of escaping from local minima. In the second approach we associate a learning set which specifies attractive and repulsive fields of output neurons. Results indicate that accuracy percentile of the new methods are higher than the original algorithm while they have the ability to escape from local minima.
