Protected Member Functions
virtual void	preNeedSample () override
	This is where most of the computations happen:

virtual bool	needSample (const std::vector< Real > &row, dof_id_type local_ind, dof_id_type global_ind, Real &val) override
	Based on the computations in preNeedSample, the decision to get more data is passed and results from the GP fills.

virtual bool	facilitateDecision () override
	This makes decisions whether to call the full model or not based on GP prediction and uncertainty.

virtual void	setupData (const std::vector< std::vector< Real > > &inputs, const std::vector< Real > &outputs)
	This sets up data for re-training the GP.

bool	learningFunction (const Real &gp_mean, const Real &gp_std) const
	This method evaluates the active learning acquisition function and returns bool that indicates whether the GP model failed.

virtual ReporterName	declareStochasticReporterClone (const Sampler &sampler, const ReporterData &from_data, const ReporterName &from_reporter, std::string prefix="") override
	This is overriden for the following reasons: 1) Only one vector can be declared and must match the type of this class.

const Sampler &	sampler () const
	Get a const reference to the sampler from the parameters.

const std::vector< std::vector< Real > > &	getGlobalInputData () const

const std::vector< Real > &	getGlobalOutputData () const
	Get a const reference to the output data.

This is overriden for the following reasons: 1) Only one vector can be declared and must match the type of this class.

2) Check that the inputted sampler matches the one given in the parameters. 3) We actually get a pointer to the declared value so we can replace it (if necessary) in the needSample routine. 4) Declare the "need_sample" value which can be used to evaluate the sample or not.

◆ sampler()

const Sampler & ActiveLearningReporterTempl< Real >::sampler ( ) const

inlineprotectedinherited

Get a const reference to the sampler from the parameters.

This is preferred over having _sampler being a protected member since we don't want derived classes changing the state of the sampler during the loop in execute.

Definition at line 57 of file ActiveLearningReporterBase.h.

57{ return _sampler; }

◆ setupData()

void ActiveLearningGPDecision::setupData	(	const std::vector< std::vector< Real > > &	inputs,
		const std::vector< Real > &	outputs
	)

protectedvirtualinherited

This sets up data for re-training the GP.

Parameters

inputs	Matrix of inputs for the current step
outputs	Vector of outputs for the current step

Definition at line 88 of file ActiveLearningGPDecision.C.

  _inputs_batch.insert(_inputs_batch.end(), inputs.begin(), inputs.end());
