> Factorization Machines have gained popularity in recent years due to their effectiveness
in recommendation systems. FMs are general predictors which allow to *capture interactions
between all features* in a features matrix. The feature matrices pertinent to the recommendation
systems are highly sparse. SystemML's highly efficient distributed sparse matrix operations
can be leveraged to implement FMs in a scalable fashion. Given the closed model equation of
FMs, the model parameters can be learned using gradient descent methods.
>  Implementation of factorization machines, as described in the paper, as a core +fm.dml+
module to support
> *  Regression
> *  Binary classification
> *  Ranking  
> We'll showcase the scalability of SystemML, with an end-to-end recommender system. Possibly,
we could integrate some other algorithms to build a state-of-the-art recommender system.
