Java-friendly version of
Run ALS with the configured parameters on an input RDD of Rating objects.
Sets the constant used in computing confidence in implicit ALS.
Set the number of blocks for both user blocks and product blocks to parallelize the computation into; pass -1 for an auto-configured number of blocks.
:: DeveloperApi :: Set period (in iterations) between checkpoints (default = 10).
:: DeveloperApi :: Sets storage level for final RDDs (user/product used in MatrixFactorizationModel).
Sets whether to use implicit preference.
:: DeveloperApi :: Sets storage level for intermediate RDDs (user/product in/out links).
Set the number of iterations to run.
Set the regularization parameter, lambda.
Set whether the least-squares problems solved at each iteration should have nonnegativity constraints.
Set the number of product blocks to parallelize the computation.
Set the rank of the feature matrices computed (number of features).
Sets a random seed to have deterministic results.
Set the number of user blocks to parallelize the computation.
