This may seem a pretty basic question but as a newbie I'd just lke to make sure. I want to apply the MetaCost operator to a binary classification and have no problem with process setup and the like. My question is how do I determine how the class labels in the cost matrix relate to my binary labels. My labels are N / L. Is Class 1 per the cost matrix simply the first label in the example set?
Is the same principle applied should there be more than 2 labels?
Thanks for your help.
