                                 throws Exception

This constructor can be used to create an instance with specified parameters.

Parameters:

starts - the number of different starts

tc - the termination condition for stopping the algorithm

threads - the number of threads that should be used during optimization

algorithm - the algorithm that shall be used

lineEps - the threshold for stopping the line search

startDist - the start distance for the line search

Throws:

Exception - if this NumericalHMMTrainingParameterSet could not be created

NumericalHMMTrainingParameterSet

public NumericalHMMTrainingParameterSet(StringBuffer xml)
                                 throws NonParsableException

The standard constructor for the interface Storable. Constructs a NumericalHMMTrainingParameterSet out of an XML representation.

Parameters:

xml - the XML representation as StringBuffer

Throws:

NonParsableException - if the NumericalHMMTrainingParameterSet could not be reconstructed out of the StringBuffer xml
