The course does not talk about how to actually fit the parameters

The new course does not discuss how the optimal parameters of the neural network are actually learned. I mean it does not discuss the cost function and backpropagation. I know the old course had this topic, then why not the new one? The old course feels cluttered to study from, so can you share some good and authoritative resources to look over these topics?

Hi @MachineMan, we discussed about it here.
