SampleSelectors

empty

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

<SampleSelector id="empty" type="EmptySampleSelector" combineOutputs="false"/>

random

Each sampling iterations new samples are selected randomly

<SampleSelector id="random" type="RandomSampleSelector" combineOutputs="false"/>

combo

Allows you combine multiple sample selector algorithms

<SampleSelector id="combo" type="CombinedSampleSelector" combineOutputs="false">
		      <SampleSelector type="RationalPoleSuppressionSampleSelector" combineOutputs="false">
		      </SampleSelector>
 
		      <SampleSelector type="DelaunaySampleSelector" combineOutputs="false">
			         <Option key="sampleSelect" value="all"/>
			         <Option key="nLastModels" value="2"/>
			         <Option key="scoreFunction" value="weightedLinear"/>
			         <Option key="lambda" value="0.5"/>
			         <Option key="mu" value="0.5"/>
			         <Option key="volumeScaling" value="max"/>
			         <Option key="differenceScaling" value="capmax"/>
			         <Option key="snapToEdge" value="enable"/>
			         <Option key="snapThreshold" value=".05"/>
		      </SampleSelector>
	   </SampleSelector>

delaunay

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

<SampleSelector id="delaunay" type="DelaunaySampleSelector" combineOutputs="false">
		      <Option key="sampleSelect" value="all"/>
		      <Option key="nLastModels" value="2"/>
		      <Option key="scoreFunction" value="weightedLinear"/>
		      <Option key="lambda" value="0.5"/>
		      <Option key="mu" value="0.5"/>
		      <Option key="volumeScaling" value="max"/>
		      <Option key="differenceScaling" value="capmax"/>
		      <Option key="snapToEdge" value="enable"/>
		      <Option key="snapThreshold" value=".2"/>
	   </SampleSelector>

density

A simple density based sample selection algorithm

<SampleSelector id="density" type="DensitySampleSelector" combineOutputs="false"/>

error

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

<SampleSelector id="error" type="ErrorSampleSelector" combineOutputs="false">
		      <Option key="nLastModels" value="4"/>
		      <Option key="differenceScaling" value="none"/>
		      <Option key="gridSize" value="50"/>
		      <Option key="maxGridSize" value="100000"/>
		      <Option key="closenessThreshold" value="0.2"/>
		      <Option key="randomPercentage" value="20"/>
	   </SampleSelector>

gradient

A highly adaptive sampling algorithm, error and density based

<SampleSelector id="gradient" type="GradientSampleSelector" combineOutputs="false">
		      <Option key="neighbourhoodSize" value="2"/>
	   </SampleSelector>

isc

A sampling algorithm aimed at optimization problems

<SampleSelector id="isc" type="InfillSamplingCriterion" combineOutputs="false">
		      <Option key="criterion" value="gei"/>
		      <Option key="g" value="1"/>
		      <Optimizer type="DirectOptimizer">
            <Option key="maxevals" value="1000"/>
            <Option key="maxits" value="300"/>
        </Optimizer>
        <Option key="debug" value="off"/>
	   </SampleSelector>
