Random Forest parameter


#1

What does it mean by node.size parameter in random forest?
How it affects results?


#2

This parameter specifies the minimum number of nodes in a leaf of the forest. Thus. no further divisions will be made in that node. This parameter implicitly gets the depth of the tree.


#3

Hi
this parameter could help to reduce the error but on the other side it will influence the overfitting. This parameter has more or less influence based on your data set.
To adjust this parameter as others build a grid and check you error metrics.
