I just have a question on the Week 2 Logistic Regression Gradient Descent lesson. I am not quite sure why dw_1 = x_1dz in the context of computing gradient descent for logistic regression. Is there a derivation that I do not yet know?

Hi @TomoCoder123 , see [image] Dw and db explanation Neural Networks and Deep Learning Yes slight_smile Using the chain rule: dL/dw1 = dL/dz * dz/dw1 = dL/dz * x1
