In mlr-org/ParamHelpers: Helpers for Parameters in Black-Box Optimization, Tuning and Machine Learning

Transform optimization path.

Description

Transform optimization path with associated transformation functions of parameters. Can only be done when x values where added “untransformed”.

Usage

trafoOptPath(opt.path)

Arguments

opt.path

[OptPath()] Optimization path.

Value

[OptPath()].

Examples

ps = makeParamSet(
  makeIntegerParam("u", trafo = function(x) 2 * x),
  makeNumericVectorParam("v", len = 2, trafo = function(x) x / sum(x)),
  makeDiscreteParam("w", values = c("a", "b"))
)
op = makeOptPathDF(ps, y.names = "y", minimize = TRUE)
addOptPathEl(op, x = list(3, c(2, 4), "a"), y = 0, dob = 1, eol = 1)
addOptPathEl(op, x = list(4, c(5, 3), "b"), y = 2, dob = 5, eol = 7)

as.data.frame(op)
op = trafoOptPath(op)
as.data.frame(op)
