CP APR algorithm which is suitable for sparse data can be implemented as well.

Is anyone else working on this? I'm taking a whack at it, trying to fit into the style of cp-als.

I have already made an implementation and test the results against of that of MATLAB tensor toolboox. I will open a pull request to move discussion there.

Do you have this implementation pushed to github somewhere? I'm in need of an implementation for a quick prototype.
