Excercise 5 - Compute Cost logprobs = np.multiply(np.log(A2),Y) cost = - np.sum(logprobs) What is the use of this piece of code ? When I copy pasted this in the exercise, I got wrong answer. cost = -np.sum(Y * np.log(A2) + (1 - Y) * np.log(1 - A2)) / m Then I tried this :point_up:, from previous…

Hello @g_paras The value of logprobs = np.multiply(np.log(A2),Y) or logprobs = Y * np.log(A2) but the given code for cost (i.e. cost = - np.sum(logprobs)) is not complete but a part of the cost. You have to compute the complete cost which you did by this: cost = -np.sum(Y * np.log(A2) + (1 - Y) …
