It's so interesting! :)<br /><br />In respect of Neural Networks, there are different tecniques we can use to adjust weights and they substantially depend from neural network topology.<br /><br />In particular there are:<br /> - Wiener-Hopf Method<br /> - Steepest Descent Method (your Gradient Algorithm)<br /> - Least-Mean-Square Algorithm (Stocastic Gradient Algorithm)<br /><br />With Kolmogorov theorem we know that each continue, limited and mototone function (with n variables) could be represented as sum of many mono-variable functions. The problem is that this is a Theorem of existence: it say that exists a set of functions but do not say how we can calculate them. For this reason we use a Neural Network.<br /><br />Bye and congratulation again.Anonymousnoreply@blogger.com
