Member Function Documentation

virtual bool init	(	DiracMixturePdf *	p,
		const std::vector< unsigned int > &	is
	)			[pure virtual]

Initialise the partitioner.

Parameters:

	p	Weighted sample set.
	is	Indices of components of interest in the weighted sample set.

Returns:

True if the partitioner is successful in finding a partition point, false otherwise. The partitioner may be unsuccessful if, e.g., all points are identical or one point in a pair has negligible small or zero weight.

Initialises the partitioner after construction, optionally using the given weighted sample set as a basis for the partition (e.g. using its bounds or covariance).

Implemented in DistributedPartitioner, LengthPartitioner, MedianPartitioner, RandomPartitioner, and VariancePartitioner.

virtual Partition assign

(

const vector &

x

)

[pure virtual]

Assign a sample to a partition.

Parameters:

x

The sample to assign.

Returns:

The partition to which the sample is assigned.

Implemented in DistributedPartitioner, LengthPartitioner, MedianPartitioner, RandomPartitioner, and VariancePartitioner.
