Subject MlLib Colaborative filtering factors
Date Tue, 25 Nov 2014 12:28:44 GMT


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?
