Hi! I did not see Prof. Andrew derive partial differentiation of J with respect to w and b but we use it in the code (graded assignment 1) and I was just wondering how to derive those formulae. Can anyone help me out? Thanks!

Hi! Thanks for the reply. But I was referring to the partial differentiation of J with respect to w and b (see below) and not the update rule. I donâ€™t see those equations in the â€śLogistics regression on m examplesâ€ť video.

Welcome to the DL Specialization @pkrishan. You need to review and study the video â€śVectorizing Logistic Regressionâ€™s Gradient Computation.â€ť
