class SVDPlusPlus extends Arguments

Implement SVD++ based on "Factorization Meets the Neighborhood: a Multifaceted Collaborative Filtering Model", available at https://dl.acm.org/citation.cfm?id=1401944.

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.

    Deprecated

    (Since version 2.12.16) Use formatString.format(value) instead of value.formatted(formatString), or use the f"" string interpolator. In Java 15 and later, formatted resolves to the new method in String which has reversed parameters.
