Apply the logistic regression with gradient descent and show only the first iteration of the algorithm. Use the learning rate =0.5, wo = 0.25, W1=2.5, W23 -3.5, W3=2.5, W X= W0 + W1X1 + W2X2 + W3X3 and assume no regularization is used. Find the value of cost function and write the complete form of the hypothesis at the end of the first iteration. No.of.SavedWishlists (X3) Is the Product Popular?
