Can anyone help? Where is the mistake? ML_Course_C3_W2

Can anyone help me?
I did mistake in the first assignment of 3 course of 2 week. The mistake related to regularization term? Where should I add regularization term? Inside for loop or outside?

Hi @sultan007755,

See the discussion here:

c3_w2_UNQ_C1 AssertionError: Wrong value. Expected 27, got 12.0

Hi @Lucky_Agrawal, Look carefully at how the cost function J looks like: [image] The regularization term is outside of the summation over i and j which means that it should be added to the J function after you exit from both for-loops (just before you divide J by 2). In your code, you added a regularization term inside the for-loop. Therefore you add it multiple times and you should add it only once.

And please delete your code. It is against Coursera rules to post an assignments code.
