Class Learner.Parameters

java.lang.Object

edu.illinois.cs.cogcomp.lbjava.learn.Learner.Parameters

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

AdaBoost.Parameters, AdaGrad.Parameters, LinearThresholdUnit.Parameters, MuxLearner.Parameters, NaiveBayes.Parameters, SparseMIRA.Parameters, SparseNetworkLearner.Parameters, StochasticGradientDescent.Parameters, SupportVectorMachine.Parameters, WekaWrapper.Parameters

Enclosing class:

Learner

public static class Learner.Parameters
extends Object
implements Serializable

Parameters classes are used to hold values for learning algorithm parameters, and all learning algorithm implementations must provide a constructor that takes such an object as input. All algorithm specific Parameters classes extend this class.

Field Detail

rounds

public int rounds

The number of rounds of training; but wait; this parameter doesn't actually affect the behavior of any learners as the number of training rounds is specified via other mechanisms. Nonetheless, it comes in handy to have it here as a communication vehicle when tuning parameters.

Constructor Detail

Parameters

public Parameters()

Sets all the default values.

Parameters

public Parameters(Learner.Parameters p)

Copy constructor.

Method Detail

setParameters

public void setParameters(Learner l)

Calls the appropriate Learner.setParameters(Parameters) method for this Parameters object.

Parameters:

l - The learner whose parameters will be set.

nonDefaultString

public String nonDefaultString()

Creates a string representation of these parameters in which only those parameters that differ from their default values are mentioned.
