Constructor Detail

CLLClassifierParameterSet

public CLLClassifierParameterSet(StringBuffer xml)
                          throws NonParsableException

The standard constructor for the interface Storable. Constructs a CLLClassifierParameterSet out of its XML representation.

Parameters:

xml - the XML representation as StringBuffer

Throws:

NonParsableException - if the CLLClassifierParameterSet could not be reconstructed out of the XML representation (the StringBuffer could not be parsed)

                          throws Exception

The default constructor that constructs a new CLLClassifierParameterSet.

Parameters:

alphabet - the AlphabetContainer

length - the length of the sequences

algo - the algorithm that shall be used for optimization

eps - the epsilon for stopping the optimization

lineps - the epsilon for stopping the line search

startD - the start distance for the line search

free - the switch for using only the free or all parameters in a ScoringFunction

kind - indicates the kind of class parameter initialization

norm - the switch for using a normalization while optimization

Throws:

Exception - if something went wrong

Method Detail

loadParameters

protected void loadParameters()
                       throws Exception

Description copied from class: ParameterSet

Loads the parameters for this ParameterSet. This is in most cases done by calling ParameterSet.initParameterList() or ParameterSet.initParameterList(int) to initialize ParameterSet.parameters and afterwards filling ParameterSet.parameters with instances of subclasses of Parameter.

Overrides:

loadParameters in class ScoreClassifierParameterSet

Throws:

Exception - if the parameters could not be loaded

See Also:

Parameter, ParameterSet.parameters, ParameterSet.initParameterList(), ParameterSet.initParameterList(int)

shouldBeNormalized

public boolean shouldBeNormalized()

This method indicates if a normalization shall be used while optimization. The normalization is done through division by the number of sequences.

Returns:

true if a normalization shall be used while optimization, false otherwise
