void | visit_at_end (RF &rf, PR &pr) |
Visitor that calculates the oob error of the random forest. this is the default visitor used.
To bored to comment each line of this class - trust me it works.
void visit_after_tree | ( | RF & | rf, |
PR & | pr, | ||
SM & | sm, | ||
ST & | st, | ||
int | index | ||
) |
does the basic calculation per tree
Reimplemented from VisitorBase.
void visit_at_end | ( | RF & | rf, |
PR & | pr | ||
) |

double return_val | ( | ) |
return a double value. The value of the first visitor encountered that has a return value is returned with the RandomForest::learn() method - or -1.0 if no return value visitor existed. This functionality basically only exists so that the OOB - visitor can return the oob error rate like in the old version of the random forest.
Reimplemented from VisitorBase.
