ANN. Calculating the cost: Figure 14.Cost Our cost will be same as before. Time for Backpropagation! Let C be the cost and A3 be our networks output.Time to define a chain rule for calculating cost with respect to the weights connected to the output (i.e. W[l]): Figure 15.Backpropagation chain rule
