Detailed Description

Initialises centroids and then assigns the responsibility for each point to its closest centroid.

Constructor & Destructor Documentation

ml::Clustering::ClosestCentroid::ClosestCentroid ( std::shared_ptr< const CentroidsInitialiser > centroids_initialiser )

Constructor.

Parameters

centroids_initialiser Non-null pointer to CentroidsInitialiser implementation used to initialise the centroids.

Exceptions

std::invalid_argument If centroids_initialiser is null.

	)		const

overridevirtual

Initialises component responsibilities.

Parameters

[in]	data	Data matrix with data points in columns.
[in,out]	prng	Pseudo-random number generator.
[in]	number_components	Number of centroids. Must be less or equal to `data.cols()`.
[out]	responsibilities	Destination matrix for component responsibilities, with `data.cols()` rows and `number_components` columns.
