NumPDFModelC
Probability density function represented using a numerical model.
include	"amma/Num/NumPDFModel.hh"
User Level:	Default
Library:	NumPDF
Example:	testNumPDF.cc
Section:	Pattern Recognition.Probability Density Functions.Implementation
In Scope:	std

Comments:
This class uses any model derived from NumModelC for representing the pdf. Note that it will be trained using (Xi,Pi) data pairs. If (Xi,ci) pairs are given, then the ci are converted to Pi using LabelToVec.

public NumPDFC

NumPDFModelC(const NumModelC & model)

Constructor

model	model to use for representing the pdf

Warning: Care must be taken when choosing a model since one could be used that is completely innappropriate for representing pdfs. There is nothing to prevent the model returning negative probabilities. There is also no constraint that the pdf integrate to unity.

NumPDFC Copy() const

Makes a deep copy

NumPDFBC & Body()

Access body.

const NumPDFBC & Body() const

Access body.

void Fit(const NumVLDataSetC & trainL)

Fits a pdf using labelled samples

void Fit(const NumVVDataSetC & trainP)

Fits a pdf using samples and corresponding class probability vectors

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

Evaluates Jacobian df(X)/dX
Note that this is not const=0 since the base class will calculate a numerical estimate of the Jacobian using differences if the member function is not overloaded in derived classes to provide an analytical solution.
