neuron is a program that allows you to build an artificial neural network with different topologies and train it on data using backpropagation. It started off after attending an online course on Neural Networks on Coursera by Prof. Geoffrey Hinton.

This program is able to use linear and logarithmic neurons. It applies biases for you automatically so you don't have to worry about them. You can also save your neural network and data into a single file, making retrieval quick and easy.

The idea here is to enable fast experimentation of neural networks and the effect of different topologies and different initial weights on training convergence.

I'd like to thank Zimmermann Stephan for his Graph Library which I currently use to display the training progress. (http://www.codeproject.com/Members/zimstep)
