LearnerAuditorFitter {mcboost}

Create an AuditorFitter from a Learner

Description

Instantiates an AuditorFitter that trains a mlr3::Learner on the data.

Value

AuditorFitter

list with items

• corr: pseudo-correlation between residuals and learner prediction.

• l: the trained learner.

Functions

• TreeAuditorFitter: Learner auditor based on rpart

• RidgeAuditorFitter: Learner auditor based on glmnet

Super class

mcboost::AuditorFitter -> LearnerAuditorFitter

Public fields

learner

LearnerPredictor
Learner used for fitting residuals.
