Hi,
I think it's either the average confidence of each tree or simply the voting result.

If would be great if you could provide the reference that was used while writing software!
In description it says, "resulting model is a voting model of all trees."
Is confidence based on number of votes received?

Thanks

Hi,
well, use ten trees and take a look at the confidence. If it equals to one of 1, 0.9, ..., 0.1, 0 then it is the voting confidence. Otherwise it will be the average confidence...
