.. _ExplorationObjective:


Exploration objective
---------------------


The objective is to learn the global behaviour of a  target variable by exploring regions with maximal uncertainty.

.. _ActiveLearning.Explorer.name:


name (str)
""""""""""
   The name of the objective. 

   Default: ``"objective"``

.. _ActiveLearning.Explorer.variable:


variable (str)
""""""""""""""
   The name of a single-output variable  that specifies the objective value. 

   Default: The first  variable in the list of all variables.

.. _ActiveLearning.Explorer.penalize_boundaries:


penalize_boundaries (bool)
""""""""""""""""""""""""""
   If true, the uncertainty is penalized by a small distance to the domain boundary. 

   Default: ``false``

.. _ActiveLearning.Explorer.min_uncertainty:


min_uncertainty (float)
"""""""""""""""""""""""
   The study is stopped if the uncertainty (square root of variance) of the objective at the last 5 sampling points was below ``min_uncertainty``. 

   Default: ``0.0``
