Constructor & Destructor Documentation

GaussianMixturePdf

(

)

Default constructor.

Initialises the mixture with zero dimensions. This should generally only be used when the object is to be restored from a serialization. Indeed, there is no other way to resize the mixture to nonzero dimensionality except by subsequently restoring from a serialization.

Definition at line 9 of file GaussianMixturePdf.cpp.

GaussianMixturePdf

(

const unsigned int

N

)

Constructor.

One or more components should be added with addComponent() after construction.

Parameters:

N

Dimensionality of the distribution.

Definition at line 13 of file GaussianMixturePdf.cpp.

GaussianMixturePdf	(	const unsigned int	K,
		const DiracMixturePdf &	p
	)

Constructor.

Parameters:

	K	Number of Gaussian components.
	p	Weighted sample set.

A K component Gaussian mixture is fit to p using Expectation- Maximisation (EM) with random initialisation.

Todo:

This has not been tested thoroughly.
