getImpFerns {Boruta} | R Documentation |
Random Ferns importance
Description
This function is intended to be given to a getImp
argument of Boruta
function to be called by the Boruta algorithm as an importance source.
Usage
getImpFerns(x, y, ...)
Arguments
x |
data frame of predictors including shadows. |
y |
response vector. |
... |
parameters passed to the underlying |
Note
Random Ferns importance calculation should be much faster than using Random Forest; however, one must first optimize the value of the depth
parameter and
it is quite likely that the number of ferns in the ensemble required for the importance to converge will be higher than the number of trees in case of Random Forest.
