std::vector< float >	m_input
	Contains all feature values of the currently loaded event.
std::vector< float >	m_spectators
	Contains all spectators values of the currently loaded event.
float	m_weight
	Contains the weight of the currently loaded event.
float	m_target
	Contains the target value of the currently loaded event.

Detailed Description

Wraps the data of a single event into a Dataset.

Mostly useful if one wants to apply an Expert to a single feature vector

Definition at line 135 of file Dataset.h.

Constructor & Destructor Documentation

SingleDataset()

SingleDataset	(	const GeneralOptions &	general_options,
		const std::vector< float > &	input,
		float	target = 1.0,
		const std::vector< float > &	spectators = std::vector<float>()
	)

Constructs a new SingleDataset.

Parameters

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

Member Function Documentation

getFeature()

virtual std::vector<float> getFeature ( unsigned int  iFeature )

inlineoverridevirtual

Returns all values (in this case only one) of one feature in a std::vector<float>

Parameters

iFeature

the position of the feature to return

Reimplemented from Dataset.

Definition at line 172 of file Dataset.h.

{ return std::vector<float> {m_input[iFeature]}; }

getFeatureIndex()

unsigned int getFeatureIndex ( const std::string &  feature )

virtualinherited

Return index of feature with the given name.

Parameters

feature

name of the feature

Definition at line 50 of file Dataset.cc.

getSpectator()

virtual std::vector<float> getSpectator ( unsigned int  iSpectator )

inlineoverridevirtual

Returns all values (in this case only one) of one spectator in a std::vector<float>

Parameters

iSpectator

the position of the spectator to return

Reimplemented from Dataset.

Definition at line 178 of file Dataset.h.
