Hi Grant,
Very good release announcement. I propose that we deprecate a lot more,
I think we should be aggressive here to pave the way for a clean and
slim 1.0 release.
I propose to additionally deprecate the following algorithms, as to my

Hi Saikat,
Great that you want to work on the ALS code. I think it is very
important to make it easier to use, ideally no knowledge of the papers

Yes, look at the assign() method which allows you to apply functions
directly to the vector.

If you need some input, it would be awesome to enhance our ALS
