Backpropagation in Neural Networks. 3. We can learn weights via SGD!To estimate the parameters of this network, we use the backpropagation algorithm: 1. Choose initial weights vk(1,m) k,m and wm(1,)jm,j. 2. For t 1, 2, 3 In a classication task with two classes, it is standard to use a neural network architecture with a single logistic output unit and the cross-entropy loss function (as opposed to, for example, the sum-of-squared loss function).This is the backpropagation algorithm.
