Class SparseWinnow.Parameters

java.lang.Object

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

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

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

All Implemented Interfaces:

Serializable

Enclosing class:

SparseWinnow

public static class SparseWinnow.Parameters
extends LinearThresholdUnit.Parameters

Simply a container for all of SparseWinnow's configurable parameters. Using instances of this class should make code more readable and constructors less complicated.
