public class ANMeaning

extends java.lang.Object

This class implements the representations of meanings. Meanings are represented as Adaptive Radial Basis Networks, though not yet completed. They actually function as prototypes The class controls the meaning and implements certain operations that can be performed on this representation.

Constructor Detail

ANMeaning

public ANMeaning()

Empty constructor

ANMeaning

public ANMeaning(int d,
                 double x)

Constructs a radial basis function (ANMeaning) for dimension d and with a center point x. Basically, it is an categorical feature at dimension d with value x

Parameters:

d - dimension

x - the feature value

Method Detail

evalY

public double evalY(int ts,
                    double x)

Function to evaluate the activation value for the given feature

Parameters:

ts - a timestamp

x - the feature value

Returns:

the activation value

notExists

public boolean notExists(java.util.List o)

Checks if the current meaning is an element of the ontology.

Parameters:

o - the ontology

Returns:

false if the meaning is in the ontology, true if not.

addLocalUnit

public void addLocalUnit(int d,
                         double x)

This function is not used currently.

updateWeights

public void updateWeights(int d,
                          double x)

This function is not used currently.

decayWeights

public boolean decayWeights()

This function is not used currently.

avgCenter

public double avgCenter()

Returns:

the center (categorical feature) of the meaning

getTargets

public IntArray getTargets()

This function is not used currently.

addTarget

public void addTarget(int a)

This function is not used currently.

getDim

public int getDim()

Returns:

the dimension of the meaning

getCover

public int getCover()

Returns:

the cover of the meaning

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

Returns:

the string representation of the meaning.
