◆ classify()

bool te::cl::MaxLikelihood::classify	(	const InputAdaptor< double > &	input,
		const std::vector< unsigned int > &	attributesIndices,
		const std::vector< double > &	inputNoDataValues,
		OutputAdaptor< unsigned int > &	output,
		const unsigned int	outputIndex,
		const unsigned int	outputNoDataValue,
		const bool	enableProgressInterface
	)

Classify an input iterated data and save the result on the output iterated data.

Parameters

input	Input data to be classified.
attributesIndices	The attributes indexes to processe from the iterated train data.
inputNoDataValues	A vector of no-data values for each attribute dimension or an empty vector if no-data values are not used.
output	Output classified data.
outputIndex	The output attribute index.
outputNoDataValue	A output label value to use when dealing with input no-data.
enableProgressInterface	Enable/disable the use of a proress interfece.

◆ getCovMatrixes()

Parameters

samples	Train data samples.
attributesIndices	The attributes indexes to processe from the iterated train data.
sampleLabels	The sample lables for each iterated train data element.
enableProgressInterface	Enable/disable the use of a proress interfece.
