PipeOpVIM_regrImp: PipeOpVIM_regrImp

Description

Implements Regression Imputation methods as mlr3 pipeline, more about RI autotune_VIM_regrImp.

Arguments

Input and Output Channels

Input and output channels are inherited from PipeOpImpute.

Parameters

The parameters include inherited from [`PipeOpImpute`], as well as:

  • id :: character(1)
    Identifier of resulting object, default "imput_VIM_regrImp".

  • robust :: logical(1)
    TRUE/FALSE: whether to use robust regression, default FALSE.

  • mod_cat :: logical(1)
    TRUE/FALSE if TRUE for categorical variables the level with the highest prediction probability is selected, otherwise it is sampled according to the probabilities, default FALSE.

  • use_imputed :: logical(1)
    TRUE/FALSe: if TURE, already imputed columns will be used to impute others, default FALSE.

  • out_fill :: character(1)
    Output log file location. If file already exists log message will be added. If NULL no log will be produced, default NULL.

)

Method clone()

The objects of this class are cloneable with this method.

Usage

Arguments

deep

Whether to make a deep clone.

Examples

Run this code
{
  graph <- PipeOpVIM_regrImp$new() %>>% mlr3learners::LearnerClassifGlmnet$new()
  graph_learner <- GraphLearner$new(graph)

  # Task with NA

  resample(tsk("pima"), graph_learner, rsmp("cv", folds = 3))
}
