public class LearnWeights
extends org.licas.Service

This class is used to learn the best values for the dynamic linking weights. It is an initial attempt at learning, by changing the weight increment or decrement values, based on earlier updates. This is an older class that has not been developed recently.

LearnWeights

public LearnWeights(java.lang.String thisPassword,
                    java.lang.String thisAdminKey)
             throws java.lang.Exception

Creates a new instance of LearnWeights.

Parameters:

thisPassword - the password to protect.

thisAdminKey - a unique key to protect loading/removal.

Throws:

java.lang.Exception - any error.

Method Detail

initialise

protected void initialise()

Initialise some values.

updateIncrementWeight

public float updateIncrementWeight(float incWeight,
                                   int totalMovedUp,
                                   int totalMovedDown)

Adjust the increment weight value based on the previous number of sources moved up or down.

Parameters:

incWeight - the current increment weight value.

totalMovedUp - number of sources currently moved up a level.

totalMovedDown - number of sources currently moved down a level.

Returns:
