Copy Constructor

Parameters:

r - Rule Rule to be copied

Rule

public Rule(DataBase dataBase)

Parameters Constructor

Parameters:

dataBase - DataBase Set of training data which is necessary to generate a rule

Method Detail

clone

public Rule clone()

Clone Function

Overrides:

clone in class java.lang.Object

Returns:

Copy of the Rule object.

asignaAntecedente

public void asignaAntecedente(int[] antecedent)

It sets the antecedent of the rule

Parameters:

antecedent - int[] Antecedent of the rule

setConsequent

public void setConsequent(int clas)

It sets the consequent of the rule

Parameters:

clas - int Class of the rule

matching

public double matching(double[] example)

Function to check if a given example matchs with the rule (the rule correctly classifies it)

Parameters:

example - int[] Example to be classified

Returns:

double 0.0 = doesn't match, >0.0 = does.

setConfidence

public void setConfidence(double conf)

It sets the confidence of the rule

Parameters:

conf - confidence of the rule

setSupport

public void setSupport(double supp)

It sets the support of the rule

Parameters:

supp - support of the rule

getConfidence

public double getConfidence()

It returns the Confidence of the rule

Returns:

double Confidence of the rule

getSupport

public double getSupport()

It returns the support of the rule

Returns:

double Support of the rule

getClas

public int getClas()

It returns the output class of the rule

Returns:

int Output class of the rule

isSubset

public boolean isSubset(Rule a)

Function to check if a given rule is a subrule of this rule

Parameters:

a - Rule Rule to be examinated

Returns:

boolean false = it isn't, true = it is.

setLabel

public void setLabel(int pos,
                     int label)

It sets the label for a given position in the antecedent (for a given attribute)

Parameters:

pos - int Location of the attribute which we want to set the label

label - int New label value to set

compareTo

public int compareTo(java.lang.Object a)

Function to compare objects of the Rule class Necessary to be able to use "sort" function It sorts in an decreasing order of laplace accuracy

Specified by:

compareTo in interface java.lang.Comparable

Parameters:

a - Rule to compare with.
