boost_control: Control Hyper-parameters for Boosting Algorithms

Description

Definition of the initial number of boosting iterations, step size and other hyper-parameters for boosting algorithms.

Usage

boost_control(mstop = 100, nu = 0.1, constraint = FALSE,
              risk = c("inbag", "oobag", "none"),
              savedata = TRUE, center = FALSE, trace = FALSE,
              save_ensembless=TRUE)

Arguments

mstop
an integer giving the number of initial boosting iterations.
nu
a double (between 0 and 1) defining the step size or shrinkage parameter.
constraint
a logical indicating whether the working responses should be restricted to $(-1, +1)$. risk{ a character indicating how the empirical risk should be computed for each boosting iteration
