Hi,

I'm looking for the predict probability functionality for binary classification task present in 2.x releases. As far as I see it is gone, is there a tendency towards getting it back?

Best regards, chris

I would suggest you to use StatModel::load<RTrees>(filename); and then use the predict of the StatModel::predict.

But instead of the pure class value I would like to have the probability of the sample(s) being part of the first class, as long as it is a 2-Class problem.

In recent version we had Random Forests' predict_prob method to do so which I am missing in latest version.

Uh, I did not know about it... Actually it is sad that it's not anymore in OpenCV 3 :(
