I am new to Deep Learning. Suppose that we have a neural network with one input layer, one output layer, and one hidden layer. Let's refer to the weights from input to hidden as w and the weights from hidden to output as v. Suppose that we have initialized w and v, and ran them through the neural network via the Feedforward algorithm. Suppose that we have calculated v via backprogagation. When estimating the ideal weights for w, do we keep the weights v constant when updating w via gradient descent given we already calculated v, or do we allow v to update along with w?
I understand that both w and v should update simultaneously when updating v, that's not my question. My question is related to if we need to update v when updating w, given we already calculated v.

During backpropogation, we first need to calculate the change in v. Then, with the help of v we will calculate the change in w.
