◆ KDEModel() [1/3]

KDEModel	(	const double	bandwidth = `1.0`,
		const double	relError = `KDEDefaultParams::relError`,
		const double	absError = `KDEDefaultParams::absError`,
		const KernelTypes	kernelType = `KernelTypes::GAUSSIAN_KERNEL`,
		const TreeTypes	treeType = `TreeTypes::KD_TREE`,
		const bool	monteCarlo = `KDEDefaultParams::mode`,
		const double	mcProb = `KDEDefaultParams::mcProb`,
		const size_t	initialSampleSize = `KDEDefaultParams::initialSampleSize`,
		const double	mcEntryCoef = `KDEDefaultParams::mcEntryCoef`,
		const double	mcBreakCoef = `KDEDefaultParams::mcBreakCoef`
	)

Initialize KDEModel.

Parameters

bandwidth	Bandwidth to use for the kernel.
relError	Maximum relative error tolerance for each point in the model. For example, 0.05 means that each value must be within 5% of the true KDE value.
absError	Maximum absolute error tolerance for each point in the model. For example, 0.1 means that for each point the value can have a maximum error of 0.1 units.
kernelType	Type of kernel to use.
treeType	Type of tree to use.
monteCarlo	Whether to use Monte Carlo estimations when possible.
Probability	of a Monte Carlo estimation to be bounded by relative error tolerance.
initialSampleSize	Initial sample size for Monte Carlo estimations.
mcEntryCoef	Coefficient to control how much larger does the amount of node descendants has to be compared to the initial sample size in order for it to be a candidate for Monte Carlo estimations.
mcBreakCoef	Coefficient to control what fraction of the node's descendants evaluated is the limit before Monte Carlo estimation recurses.

◆ KDEModel() [2/3]

◆ BuildModel()

void BuildModel ( arma::mat && referenceSet )

Build the KDE model with the given parameters and then trains it with the given reference data.
