thank you for your coding. I have studied on yours.

at mf.py on line 94;

[Now] return mf.b + self.b_u[:,np.newaxis] + mf.b_i[np.newaxis:,] + mf.P.dot(mf.Q.T)
[Collect?] return self.b + self.b_u[:,np.newaxis] + self.b_i[np.newaxis:,] + self.P.dot(self.Q.T)

good bye.

Hello sir,
I believe there is a minor error in the code.
I believe the code you write still passed by reference instead of value. Since is a array generate by numpy, not a list.

By the way, well written article and code. It really helped me to tie all the concepts that I have learned! Thank you very much!
