Abstract

This paper compares two Self-Organizing Map (SOM) based approaches for temporal sequence processing: The Recurrent Self-Organizing Map (RSOM) and Temporal Kohonen Map (TKM). The convergence properties of these algorithms are studied, and their difference in learning is emphasized both theoretically and with simulations. The results show that RSOM is superior over TKM.
