Learning XOR is the hello world of neural networks (NNs) using supervised learning. I've added a few more logic gates to the example code, including NOT that requires 1 instead of 2 neurons in the input and hidden layer. Also optimized/refactored it a little, and added own display of the truth table from the 2D-arrays with the training data (INPUT) and the ideal data (IDEAL). The Resilient Propagation (1992) is more efficient and modern than the Backpropagation (1970s) learning algorithm.
