localSurrogate {distillML}

R Documentation

Given a interpreter object with at least one pair of features, create a small surrogate model for the two features using the PDP function as the output and the two features as the independent variables.

Plots and returns a Rforestry object with a single tree explaining the PDP surface.

localSurrogate(
  object,
  features.2d = NULL,
  interact = FALSE,
  params.forestry = list()
)

`object`	Interpreter object to make plots + surrogate for.
`features.2d`	A two-column dataframe of pairs of features to make local surrogates for. Each row represents a pair of features, with the names of features as the entries.
`interact`	An indicator specifying if the surrogate model should also be given the interaction terms to create the surrogate models with. Default is FALSE.
`params.forestry`	Optional list of parameters to pass to the surrogate model. Defaults to the standard Rforestry parameters with ntree = 1 and maxDepth = 2.

A list of two distinct lists: one list contains the local surrogate models, and the other containing the 2-D PDP plots for the specified features.
