validation and meta cost
What I would like to do is attach costs to the model -- namely making it more costly to say that a student at risk will be fine -- but when I add the metacost operator and move the DT operator into it RM gives me an error:
P Aug 23, 2008 11:32:42 PM: Test: Set parameters for com.rapidminer.operator.learner.meta.MetaCostModelThat snippet is from the log set in verbose mode, so I am wondering if I am just trying to do something invalid, if I have something out of order, or if I just don't know what I am doing. Thanks, --chris
