Gini Index Random Forest
Contributor II
Hi,
whenever I try using the gini index option for the Random Forest the process breaks down due to memory issues. Even if I only use something like 7000 examples, 15 Attrubutes and 2 classes for which all other options work fine. Is that a known bug or just due to the method?

please restrict the maximal tree depth and minimal number of examples per leaf to cut tree building. Might be it "explodes" exponentially.

if it can explode depends on your data: If you have many nominal values, the tree size can be much greater than if all attributes are numerical and there can be only a split into two branches...
