HI, I am trying to execute Collaborative filtering using MlLib. Can somebody please suggest how to calculate the following
1. Rank 2. Iterations 3. Lambda I understand these are adjustment factors and they help reduce the MSE in turn defining accuracy of algorithm but then is it all hit and trial or is there a definitive way to calculate them?
