Hi,
In the assignment, when implement the no regularization formula I get correct results for the first output but not the regularized ones. when I do implement the regularizaiton formula, I get zero for the non-regularized term (which is expected actually since it multiplies all with 0) but the rest of the output is wro

ng as well. I have a hard time understanding what is wrong here, is the suggested formula wrong?
Urgent help needed, thanks! 
Here is a starting point for you to consider:
Your code is computing w and b_j, and x, y, and r, but you aren’t using any of them. What is your strategy in this code?
Hi @TMosh ,
Thanks for the feedback, I have been actually trying out different cost functions and this is just one of them since it was in the solutions. I think we need to add the regularization to the cost function as in the description formulas but that doesn’t work either, ie.

which should correspond to this?
You are adding the regularized term to the cost nu*nm times instead of once. Please compute the regularized term outside the loops.
I’m removing the code from the thread, as that’s not allowed by the code of conduct.
