decision_tree_probabilities: Decision tree Prediction

In mlpack: 'Rcpp' Integration for the 'mlpack' Library

Decision tree Prediction

Description

Class predictions from train decision tree model.

Usage

decision_tree_probabilities(
  input_model,
  test,
  test_labels = NA,
  verbose = getOption("mlpack.verbose", FALSE)
)

Arguments

input_model	Pre-trained decision tree, to be used with test points (DecisionTreeModel).
test	Testing dataset (may contain categorical variables) (numeric matrix/data.frame with info).
test_labels	Test point labels, if accuracy calculation is desired (integer row).
verbose	Display informational messages and the full list of parameters and timers at the end of execution. Default value "getOption("mlpack.verbose", FALSE)" (logical).

Value

A list with several components defining the class attributes:

probabilities

Class probabilities for each test point if probabilities has been selected (numeric matrix).
