Method Detail

getVectorDictionary

public static VectorDictionary getVectorDictionary(org.w3c.dom.Element container,
                                                   MiningSchema ms)
                                            throws java.lang.Exception

Returns a new VectorDictionary constructed from the supplied XML container

Parameters:

container - the containing XML

ms - the mining schema

Returns:

a VectorDictionary

Throws:

java.lang.Exception - if the VectorDictionary can't be read from the XML container

incomingInstanceToVectorFieldVals

public double[] incomingInstanceToVectorFieldVals(double[] incoming)
                                           throws java.lang.Exception

Convert an incoming instance to an array of values that corresponds to the fields referenced by the support vectors in the vector dictionary

Parameters:

incoming - an incoming instance

Returns:

an array of values from the incoming instance that corresponds to just the fields referenced by the support vectors

Throws:

java.lang.Exception - if this array cant be constructed for some reason

getVector

public VectorInstance getVector(java.lang.String ID)

Gets a vector from the dictionary corresponding to the supplied ID

Parameters:

ID - the ID of the vector to retrieve

Returns:

the vector with the given ID or null if no vector with that ID exists in the dictionary
