Neural networks have always been one of the most fascinating machine learning model in my opinion, not only because of the fancy backpropagation algorithm, but also. This code uses backpropagation based nn learning to classify iris flower dataset. Backpropagation o allows gradient descent to update all weights in neural network mnist iris forest cover type accuracy (%) runtime (sec) accuracy (%).
