mlr_learners_regr.simple_linear_regression: Regression SimpleLinearRegression Learner from Weka

In mlr-org/mlr3extralearners: Extra Learners For mlr3

Regression SimpleLinearRegression Learner from Weka

Description

Simple linear regression model that picks the attribute that results in the lowest squared error. Calls RWeka::make_Weka_classifier() from RWeka.

Custom mlr3 parameters

• output_debug_info:

  • original id: output-debug-info

• do_not_check_capabilities:

  • original id: do-not-check-capabilities

• num_decimal_places:

  • original id: num-decimal-places

• batch_size:

  • original id: batch-size

• additional_stats:

  • original id: additional-stats

• Reason for change: This learner contains changed ids of the following control arguments since their ids contain irregular pattern

Dictionary

This Learner can be instantiated via the dictionary mlr_learners or with the associated sugar function lrn():
