mlr_pipeops_targetinvert {mlr3pipelines}R Documentation

Invert Target Transformations

Description

Inverts target-transformations done during training based on a supplied inversion function. Typically should be used in combination with a subclass of PipeOpTargetTrafo.

During prediction phase the function supplied through "fun" is called with a list containing the "prediction" as a single element, and should return a list with a single element (a Prediction) that is returned by PipeOpTargetInvert.

Format

R6Class object inheriting from PipeOp.

Construction

PipeOpTargetInvert$new(id = "targetinvert", param_vals = list())

Input and Output Channels

PipeOpTargetInvert has two input channels named "fun" and "prediction". During training, both take NULL as input. During prediction, "fun" takes a function and "prediction" takes a Prediction.

PipeOpTargetInvert has one output channel named "output" and returns NULL during training and a Prediction during prediction.

State

The ⁠$state⁠ is left empty (list()).

Parameters

PipeOpTargetInvert has no parameters.

Internals

Should be used in combination with a subclass of PipeOpTargetTrafo.

Fields

Only fields inherited from PipeOp.

Methods

Only methods inherited from PipeOp.
