plotBaselearner: Visualize contribution of one base learner

In schalkdaniel/compboost: Efficient Component-Wise Boosting Implementation

Visualize contribution of one base learner

Description

This function visualizes the contribution of a base learner to the overall prediction score. For visualization of partial effects see plotPEUni().

Usage

plotBaselearner(cboost, blname, npoints = 100L)

Arguments

cboost	(Compboost) A trained Compboost object.
blname	(character(1L)) Name of the base learner. Must be one of cboost$getBaselearnerNames().
npoints	(integer(1L)) Number of points which are predicted for the lines (only applies to numerical features).

Value

ggplot object containing the graphic.

Examples

cboost = Compboost$new(data = iris, target = "Petal.Length",
  loss = LossQuadratic$new())
cboost$addComponents("Sepal.Width")
cboost$train(500L)
plotBaselearner(cboost, "Sepal.Width_linear")
plotBaselearner(cboost, "Sepal.Width_Sepal.Width_spline_centered")
