Finally multiply the end product with 1/m , where m is the number of training examples.This is the vectorized implementation of the code that's actually way more lengthier to implement using loops.

Made for sharing. can someone please explain?
topic, visit your repo's landing page and select "manage topics.". why didn't you use sum() function for grad even why formula contains that ?
Opening and closing brackets are not matching you code.NOTE: check the brackets are "2*m"YOUR CODE: reg_term = (lambda/2*m)) * sum(theta(2:end).^2);WORKING CODE: reg_term = (lambda/(2*m)) * sum(theta(2:end).^2); Hello Akshay,While computing cost function I am getting so many outputs. Before starting on the programming exercise, we strongly recommend watching the video lectures and completing the review questions for the associated topics.

In this gradient decent the number of iteration are not specified so how is the gradient decent working? Also, recall we cannot use space in the script’s name. Problem set grading will be done coarsely (i.e.
