Answer:



Feedforward, Fully connected, 3 layer neural networks, generally using Sigmoid function as the transfer function with backpropagation for training purposes.



Basically you set up a neural network say 49, 58, 26 nodes in 3 layers. Feed in the visual input into the input layer and recieve the output from the output layer.



The network is trained on perfect training data (A, B, C, D, etc) using a backpropagation algorithm.



If none of this makes sense to you then look up Neural networks in google or look at one of the sources below.



Basically a neural network is a collection of simple processing units called nodes that are connected together to form networks.



These networks aren't programmed in the traditional sense, instead they are trained on data until the answers it gives closely match the expected results given the inputs.



When the network falls below a given error value the training stops.



The network should have flexibility to now recognise the training data and still match any pattern resembling the training data.
