As per operator description, If this parameter is set to true then *int(log(m) + 1) Attributes are selected. What is int? And Please demonstrate this with the help of an example.

    Hi @pakizahfatima,
    int is rather round here. It is the setting to decide how many features are available at each node of the RF. If you have 10 attributes in total you get:
    k = int(log(10)+1) = int(1+1) = int(2) = 2 
    as a result.


    Best,
    Martin
