NeuralNet is a GUI to the designing, training, and evaluating of neural networks using the backpropagation training algorithm. Simple sample network, pattern, and weights files are included. No explanation of the file formats are included except the pattern files, which are explained in the help file supplied with the program. The point being that the program takes care of the generation of the other two files, network and weights, for the user. The pattern files must be created by the user. All file formats are in text (ASCII).
