Comments:
Class for representing class labels for classification. Slightly limited approach means that they are assumed to be incrementing unsigned integers but this is required to facilitate access to a vector of corresponding class probabilities.

Base class in the PatternRec hierarchy and is used in conjunction with classification objects derived from NumClassifyC for representing class labels.

UIntT _label;

NumLabelC()

Default constructor
Label value is undefined.

NumLabelC(UIntT label)

Constructor with label value

NumLabelC(istream & in)

Constructs from stream

NumLabelC(const VectorC & oth)

Constructs from probability vector
Converts from vector to label using VecToLabel.

NumLabelC(const NumLabelC & oth)

Copy constructor

BooleanT operator==(const NumLabelC & oth) const

Equality operator

BooleanT operator!=(const NumLabelC & oth) const

Inequality operator

NumLabelC Copy() const

Makes a copy, needed for containers

void Save(ostream & out) const

Writes object to stream, can be loaded using constructor

int LessOrEqual(const NumLabelC & oth) const

Compares two labels, used for sorting

IndexT AsIndex() const

Treats label as an index for accessing probability vectors

UIntT AsUIntT() const

Converts label to unsigned integer

void SetInvalid()

Set this label to an invalid value.

BooleanT IsInvalid() const

Is this an invalid label ?

UIntT Hash() const

Get hash value for label.

UIntT MaxOf(UIntT val) const

Returns maximum of current label and val

VectorC LabelToVec(const NumLabelC & L,UIntT maxLabel,RealT minP = 0.0,RealT maxP = 1.0)
