I'm looking to change the performance metric used to optimize the training for my data set because it is highly unbalance. Because it's highly unbalanced, I don't feel like accuracy is the appropriate metric to optimize and I can't seem to be able to find how to change it in the random-forest documentation.

What parameter do I have to change in the function in order to optimize according to Cohen's kappa for example?
