NumClassifyFuzzyCmeansC
Fuzzy C-means clustering algorithm
include	"amma/Num/NumClassifyFuzzyCmeans.hh"
User Level:	Default
Library:	NumClassify
Example:	testNumClassify.cc
Section:	Pattern Recognition.Clustering.Implementation
In Scope:	std

Comments:
Unsupervised classification algorithm which performs fuzzy C-means clustering. It is necessary to specify the number of classes that are expected. Initial class centres are determined by assigning each sample random membership to the class centres.

public NumClassifyUnsupervisedC

NumClassifyFuzzyCmeansC(UIntT numClasses,const NumMagnitudeC & distance,RealT m = 2.0)

Constructor

numClasses	number of classes or clusters to look for
distance	metric to use when measuring sample distance from class centres
m	class membership weighting exponent

NumClassifyUnsupervisedC Copy() const

Makes a deep copy

BooleanT IsA(const DPEntityC & pb)

Check if an object is a NumFuncConstant.

NumClassifyUnsupervisedBC & Body()

Access body.

const NumClassifyUnsupervisedBC & Body() const

Access body.

void Initialise(UIntT numClasses,const DListC<VectorC> & trainX)

Initialises the clusters

numClasses	number of clusters that will be set up
trainX	training samples used to determine initial centers

void Cluster(const DListC<VectorC> & trainX)

Used to train the classifier by clustering on unlabelled samples

NumClassifyBC & Body()

Access body.

const NumClassifyBC & Body() const

Access body.

BooleanT IsA(const DPEntityC & pb)

Check if an object is a one of these.

NumClassifyC Copy() const

Makes a deep copy

NumLabelC Classify(const VectorC & X) const

Returns the class label corresponding to the feature vector X

DListC<NumLabelC> Classify(const DListC<VectorC> & listX) const

Returns class labels corresponding to a list of X

BooleanT IsA(const DPEntityC & pb)

Check if an object is a NumFuncC.

NumFuncC Copy() const

Makes a deep copy

NumFuncC & operator=(const NumFuncC & oth)

Assignment operator

VectorC Evaluate(const VectorC & X) const

Evaluates function Y=f(X)

DListC<VectorC> Evaluate(const DListC<VectorC> & listX) const

Evaluates function Y=f(X) for a list of X

VectorC operator()(const VectorC & X) const

Evaluates function Y=f(X)

MatrixC Jacobian(const VectorC & X) const
