Constructor Detail

DataBase

public DataBase()

Default constructor. None attribute will be initialized.

DataBase

public DataBase(int nLabels,
                myDataset train)

Parameters Constructor

Parameters:

nLabels - It is the number of membership functions for each real/integer variable

train - It contains the train data set with the whole information to execute the algorithm

Method Detail

numVariables

public int numVariables()

It returns the number of input attributes in the examples

Returns:

The number of input attributes

numLabels

public int numLabels(int variable)

It returns the number of different labels that a specific input attribute can hold

Parameters:

variable - The input attribute which we want to know the number of different labels it can have

Returns:

The number of labels

getnLabels

public int[] getnLabels()

It return the whole array of number of labels for every attribute

Returns:

the whole array of number of labels for every attribute

matching

public double matching(int variable,
                       int label,
                       double value)

It checks if the value of a specific label in a specific attribute matchs with a given value

Parameters:

variable - Attribute which we are going to check

label - Attribute's label we are going to check

value - Value to be compared

Returns:

int 1 = Don't care, [0.0,1.0] = another one.

print_triangle

public java.lang.String print_triangle(int var,
                                       int label)

Return a String representation of the Triangular Membership Functions of the variable and its label given as arguments.

Parameters:

var - Index of the variable given.

label - Index of the label given.

Returns:

String representation of the Triangular Membership Function.

print

public java.lang.String print(int var,
                              int label)

It prints an attribute with its label in a string way

Parameters:

var - Attribute to be printed

label - Attribute's label to be printed

Returns:

A string which represents the "string format" of the given input

printString
