Hi, I'm wondering has someone tried ParallelALS with implicite feedback job on million song dataset? Some pointers on alpha and lambda?
In the paper alpha is 40 and lambda is 150, but I don't know what are their r values in the matrix. They said is based on time units that users have watched the show, so may be it's big.
