Constructor Detail

Rule

public Rule(int nAtributos)

Default builder

Parameters:

nAtributos - Number of antecedents of the rule

Rule

public Rule(int nAtributos,
            int clas,
            double fuerza)

Rule Builder

Parameters:

nAtributos - Number of antecedents of the rule

clas - class in the consequent of the rule

fuerza - Significance of the rule

Method Detail

compareTo

public int compareTo(java.lang.Object o)

It compares the rule with respect to their strength

Specified by:

compareTo in interface java.lang.Comparable

Parameters:

o - Another rule object

Returns:

0 if they have the same strength, 1 if the parameter rule is stronger, -1 in the contrary case

print

public void print()

It prints the rule

printString

public java.lang.String printString()

It prints the rule into a string

Returns:

a string with the rule content

copyRule

public Rule copyRule()

It performs a copy of the rule

Returns:

an exact copy of the antecedent of the rule

setClas

public void setClas(int clas)

It assigns a new class for the rule

Parameters:

clas - the new class

getClas

public int getClas()

It returns the consequent class of the rule

Returns:

the consequent class of the rule

setCondition

public void setCondition(Condition c)

It adds a new condition to the rule

Parameters:

c - the condition

setStrength

public void setStrength(double strength)

It assigns a new strength to the rule

Parameters:

strength - the new strength

getStrength

public double getStrength()

It gets the strength of the rule

Returns:

the strength of the rule

getCondition

public Condition getCondition(int i)

It returns a condition defined for the i-th attribute

Parameters:

i - attribute id

Returns:

the condition

isEqual

public boolean isEqual(Rule r)

It checks if the rule is equal to another

Parameters:

r - Rule for comparison

Returns:

True if both rules are the same, false in other case

addAttributeNames

public void addAttributeNames(java.lang.String[] atributos)

It stores the names of the input attributes

Parameters:

atributos - String[] an Array that stores the name of each variable

Parameters:

className - String name of the class attribute

addClassNames

public void addClassNames(java.lang.String[] classes)

It stores the names of the output attribute

Parameters:

classes - String[] an Array that stores the name of the classes of the problem

addValuesNames

public void addValuesNames(java.lang.String[][] valores)

It stores the name for the different values in the data-set

Parameters:

valores - String[][] the name for the different values in the data-set

setMinValues
