simple single-layer (if you don't count the output layer) neural network for guessing numbers from images. It's not great, sometimes it has dificulties with recognising the number right, especialy with 8. For best results try to draw the number in the center and so it fills the whole frame You can also click 0, 1, 2, 3... itc. to save the current image to the training data for its corresponding number accuracy - the activation of the output neuron (passed throught a sigmoid function) bias - value substracted from the sum of input neurons * weights, used to fine tune the network
