class SVDPlusPlus extends Arguments

Implement SVD++ based on "Factorization Meets the Neighborhood: a Multifaceted Collaborative Filtering Model", available at https://movie-datamining.googlecode.com/svn/trunk/kdd08koren.pdf.

Note: The status of this algorithm is EXPERIMENTAL. Its API and implementation may be changed in the future.

The prediction rule is rui = u + bu + bi + qi*(pu + |N(u)|-0.5*sum(y)). See the details on page 6 of the article.

Configuration parameters: see the description of each parameter in the article.

Returns a DataFrame with vertex attributes containing the trained model. See the object (static) members for the names of the output columns.
