I also tested the SVDPlusPlus on movielens-100k dataset. The algorithm just
diverged. And the mse on the dataset gets 2.14748364347152E9.
I tested @lxmly 's code as well, it works but I don't know whether it is
proper to use the 'mean gradient'.
@lxmly How do you get the conclusion 'using mean gradient'? Any reference?
Thanks in advance.
