Class SingleDelta

java.lang.Object

com.ibm.bluej.consistency.learning.SingleDelta

All Implemented Interfaces:

IDeltaWeight

public class SingleDelta
extends java.lang.Object
implements IDeltaWeight

Only makes sense if doing MAP inference and learning at the same time Otherwise either DeltaOnly or FixedDeltaWeight is the right choice
