Convergence of the and synaptic weight vectors through time.

<p>Results are shown for the current model and for a previous model by the authors <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0058330#pone.0058330-Walters1" target="_blank">[22]</a>. The plots display the root mean square (RMS) change in the synaptic weights across successive blocks of five training epochs for either the connections (left plot) or connections (right plot). For both models, the RMS change in the weights is monotonically decreasing after about 10–15 epochs. This implies that both the and synaptic weights are asymptotically converging to steady values. However, it is evident that convergence of the synaptic weights is much more rapid for the current model than the model of <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0058330#pone.0058330-Walters1" target="_blank">[22]</a>.
