mlr_tuners_gensa

Subclass for generalized simulated annealing tuning calling <code><a rd-options="GenSA:GenSA" href="/link/GenSA%3A%3AGenSA()?package=mlr3tuning&version=0.1.0&to=GenSA%3AGenSA" data-mini-rdoc="GenSA:GenSA::GenSA::GenSA()">GenSA::GenSA()</a></code> from package GenSA.

datasets

Implements methods for hyperparameter tuning with
'mlr3', e.g. Grid Search, Random Search, or Simulated Annealing.
Various termination criteria can be set and combined.  The class
'AutoTuner' provides a convenient way to perform nested resampling in
combination with 'mlr3'.

Construction

This tuner currently supports the following hyperparameters:<ul>
<li><code>smooth</code> :: <code>logical(1)</code></li>
<li><code>temperature</code> :: <code>numeric(1)</code></li>
<li><code>acceptance.param</code> :: <code>numeric(1)</code></li>
<li><code>verbose</code> :: <code>logical(1)</code></li>
<li><code>trace.mat</code> :: <code>logical(1)</code></li>
</ul>For the meaning of the control parameters, see <code><a rd-options="GenSA:GenSA" href="/link/GenSA%3A%3AGenSA()?package=mlr3tuning&version=0.1.0&to=GenSA%3AGenSA" data-mini-rdoc="GenSA:GenSA::GenSA::GenSA()">GenSA::GenSA()</a></code>.
Note that we have removed all control parameters which refer to the termination of the algorithm and
where our terminators allow to obtain the same behavior.

Parameters

Subclass for generalized simulated annealing tuning calling <code><a rd-options='GenSA:GenSA' href='GenSA::GenSA()'>GenSA::GenSA()</a></code> from package GenSA.
