task

[<code>data.frame</code>]
A data frame containing the features and target variable.
If missing, <code>task</code> must be supplied.

data

[<code>character(1)</code>]
Name of the target variable.

target


Estimate the residual variance of a regression model on a given task.
If a regression learner is provided instead of a model, the model is
trained (see <code><a rd-options="" href="/link/train?package=mlr&version=2.9" data-mini-rdoc="mlr::train">train</a></code>) first.


Interface to a large number of classification and regression
techniques, including machine-readable parameter descriptions. There is
also an experimental extension for survival analysis, clustering and
general, example-specific cost-sensitive learning. Generic resampling,
including cross-validation, bootstrapping and subsampling. Hyperparameter
tuning with modern optimization techniques, for single- and multi-objective
problems. Filter and wrapper methods for feature selection. Extension of
basic learners with additional operations common in machine learning, also
allowing for easy nested resampling. Most operations can be parallelized.
