SampleSelector

empty

Dont select any new samples, useful when modeling multiple outputs in paralel

<[[Config:SampleSelector|SampleSelector]] type="[[SampleSelector:EmptySampleSelector|EmptySampleSelector]]" combineOutputs="false"/>

random

Each sampling iterations new samples are selected randomly

<[[Config:SampleSelector|SampleSelector]] type="[[SampleSelector:RandomSampleSelector|RandomSampleSelector]]" combineOutputs="false"/>

combo

Allows you combine multiple sample selector algorithms

<[[Config:SampleSelector|SampleSelector]] type="[[SampleSelector:CombinedSampleSelector|CombinedSampleSelector]]" combineOutputs="false">
   <[[Config:SampleSelector|SampleSelector]] type="[[SampleSelector:RationalPoleSuppressionSampleSelector|RationalPoleSuppressionSampleSelector]]" combineOutputs="false"><!-- Currently no options are available, if the model is a rational model, and a
 - - pole is found (using a simple search strategy), the pole is returned --></[[Config:SampleSelector|SampleSelector]]>

delaunay

An adaptive sample selection algorithm that does a trade-off between error and density

density

A simple density based sample selection algorithm

error

An adaptive sample selection algorithm (error based), driven by the evaluation of your model on a dense grid

   <Option key="closenessThreshold" value="0.2"/><!-- Set a % of the maximumSamples to randomly chosen -->
   <Option key="randomPercentage" value="20"/>
