transform_xdt_to_xss

Calculates the transformed x-values

Description

Transforms a given data.table() to a list with transformed x values. If no trafo is defined it will just convert the data.table() to a list. Mainly for internal usage.

Usage

transform_xdt_to_xss(xdt, search_space)

Arguments

`xdt`	(`data.table::data.table()`) Set of untransformed points / points from the search space. One point per row, e.g. `data.table(x1 = c(1, 3), x2 = c(2, 4))`. Column names have to match ids of the `search_space`. However, `xdt` can contain additional columns.
`search_space`	(paradox::ParamSet) Specifies the search space for the Optimizer. The paradox::ParamSet describes either a subset of the `domain` of the Objective or it describes a set of parameters together with a `trafo` function that transforms values from the search space to values of the domain. Depending on the context, this value defaults to the domain of the objective.

Value

list().
