Detailed Description

Wraps the data of a multiple event into a Dataset.

Mostly useful if one wants to apply an Expert to a feature matrix

Definition at line 186 of file Dataset.h.

Constructor & Destructor Documentation

MultiDataset()

MultiDataset	(	const GeneralOptions &	general_options,
		const std::vector< std::vector< float >> &	input,
		const std::vector< std::vector< float >> &	spectators,
		const std::vector< float > &	targets = {},
		const std::vector< float > &	weights = {}
	)

Constructs a new MultiDataset.

Parameters

general_options	which defines e.g. number of variables
input	feature values of the single event
spectators	spectator values of the single event
targets	target values of the single event (defaults to 1, because often this is not known if one wants to apply an expert)
weights	weights assigned to the input feature values

Definition at line 145 of file Dataset.cc.

Member Function Documentation
