Default Re: *ANSWER* questions w linear regression & weight decay

Are you using the correct formula for the one step solution?

I was using (Z^T Z - \lambda I)\ldots instead of (Z^T Z + \lambda I)\ldots and so regularization didnt make sense at all. I caught the error because I saw in another post that Professor Yaser corrected a student on the plus sign.
