dot-list_to_PreprocessorConfig: Convert a list to a PreprocessorConfig object

In rtemis: Schema-Driven Machine Learning and Visualization

Convert a list to a PreprocessorConfig object

Description

Internal function used to reconstruct a PreprocessorConfig object from a named list, such as the result of parsing a JSON config conforming to the schema.rtemis.org preprocessor schema. Elements are passed to setup_Preprocessor; document metadata (⁠$schema⁠) is dropped first, since it identifies the document.

Usage

.list_to_PreprocessorConfig(x)

Arguments

x	Named list of setup_Preprocessor parameters.

Details

The learned values (impute_numeric_values, impute_level_values, scale_centers, scale_coefficients, one_hot_levels, factor2integer_levels) are data_dependent settable inputs: a user-authored config typically carries none, and the ⁠setup_*⁠ defaults leave them unset. A config that does carry them – a fitted preprocessor written back out – restores them, which is why they are serialized at all (see "Property roles" in ⁠010_Props.R⁠).

Value

A PreprocessorConfig object.
