Artificial Neural Networks are a mathematical representation of the biological Neural Networks whitch are more sophisticated and more complicated. - they can compute any computable function and they are very useful for classification. - they are issued from the need to build artificial systems capable of sophisticated or intelligent computations similar to those that the human brain routinely performs. Topologicaly there is Two major kinds of networks : Feedforward and Feedback. - In a Feedforward NN, the connections between units do not form cycles. They usually produce a response to an input quickly. they are restricted to finite-dimensional input and output spaces. - In a feedback or recurrent NN, there are cycles in the connections. In some feedback NNs, each time an input is presented, the NN must iterate for a potentially long time before it produces a response. Feedback NNs are usually more difficult to train than feedforward NNs. Here I use a FeedForward Neural Network to show how it recognize a character. there is four NNs, the first one to classify the character; is it a (Capital, Small or punctuation letter)? and other three NNs, one for each class. they have been trained before so, this code will show how to use them after been trained. for any suggestion or question feel free to email me bcwan@multimania.com
