Hi Isam,

I am not sure whether you already know how neural networks work or not. Basically, RBF networks is simply neural networks which use Gaussian function as their activation function in each node (unit). In case that you are not familiar with how neural networks work, you may search for Backpropagation algorithm.

For more information about RBF,

Thanksa lot Ekarin for very useful information. I am familiar with ANN but i want to use RBF for forecasting 9if you have more content.  Will read carefully and review.

3 articles on RBFNN..

Youssef, Hi man highly appreciated.
