Re: Random Forest model (number of trees)

> If I am using the Random Forest model, how many trees will it have and how many variables would be available for each tree node? I think the default number of trees in Weka is 100 but in that case, how many variables for each tree node?

Copy/paste from the "More" dialog:

numFeatures -- Sets the number of randomly chosen attributes. If 0,
int(log_2(#predictors) + 1) is used.
