TaskGenerator: TaskGenerator Class

In mllg/mlr3: Machine Learning in R - Next Generation

Description

Creates a Task of arbitrary size. Predefined task generators are stored in the mlr3misc::Dictionary mlr_task_generators, e.g. xor.

Format

R6::R6Class object.

Construction

g = TaskGenerator$new(id, task_type, packages = character(), param_set = ParamSet$new())

• id :: character(1)
  Identifier for the learner.

• task_type :: character(1)
  Type of the task the learner can operator on. E.g., "classif" or "regr".

• packages :: character()
  Set of required packages. Note that these packages will be loaded via requireNamespace(), and are not attached.

• param_set :: paradox::ParamSet
  Set of hyperparameters.

Fields

• id :: character(1)
  Identifier of the learner.

• packages :: character()
  Stores the names of required packages.

• param_set :: paradox::ParamSet
  Description of available hyperparameters and hyperparameter settings.

• task_type :: character(1)
  Stores the type of class this learner can operate on, e.g. "classif" or "regr". A complete list of task types is stored in mlr_reflections$task_types$type.

Methods

• generate(n)
integer(1) -> Task
  Creates a task of type task_type with n observations, possibly using additional settings stored in param_set.
