Re: query on SVD++

[张志强(旺轩)]

Yes,

 

We already used ALS in our production environment, we also want to try SVD++ 
but it has no python interface.

 

Any idea? Thanks

You means the SVDPlusPlus in GraphX? If you want to use SVD++ to train CF 
model, I recommend you to use ALS which is more efficiency and has python 
interface.

Hi All,

 

I came across the SVD++ algorithm implementation in Spark code base, but I was 
wondering why we didn’t expose the scala api interface to python?

Any plan to do this?
