Method Detail

setLost

public static void setLost(int example,
                           int pos)

Sets the value of the gen of an example as an lost value lost = max value of the variable + 1

Parameters:

example - Position of the example in the dataset

pos - Position of the variable

getLost

public static boolean getLost(int example,
                              int pos)

Returns if the value of the gen of an example is a lost value or not lost = max value of the variable + 1

Parameters:

example - Position of the example in the dataset

pos - Position of the variable

Returns:

If the example is a lost value

CaptureDataset

public static void CaptureDataset(java.lang.String input_file)
                           throws java.io.IOException

Dataset interpretation - read the dataset and stores the values The attribute designed in "outputs" at the dataset file is the target variable If it is not established, the last one is taken as output - defined in the methods that manages the dataset. All the variables except this are stored in "tabla.ejemplo" Target variable is stored in "tabla.clase"

Parameters:

input_file - Fichero to capture

Throws:

java.io.IOException - if the file can not be read.

getNumAttribute

public static int getNumAttribute(java.lang.String _name)

It returns the number (position) of the attribute name indicated.

Parameters:

_name - Name of the attribute.

Returns:

Position of the attribute.

CaptureRules

public static void CaptureRules(java.lang.String nFile)
                         throws java.io.IOException

Generate the population with the rules obtained by the algorithm

Parameters:

nFile - Files of the rules obtained by the algorithm

Throws:

java.io.IOException - if the file can not be read.

CaptureNumRules

public static int CaptureNumRules(java.lang.String nFile)
                           throws java.io.IOException

Return the number of rules obtained by the algorithm

Parameters:

nFile - Files of rules obtained by the algorithm

Returns:

The number of rules obtained by the algorithm

Throws:

java.io.IOException - if the file can not be read.

Calculate

public static void Calculate(java.lang.String output_file_tra,
                             java.lang.String output_file_tst,
                             java.lang.String input_file_tra,

                             java.lang.String rule_file,
                             java.lang.String quality_file,
                             int nlabels)
                      throws java.lang.Exception

Calculate is the main method of the Calculate

Parameters:

output_file_tra - Name of the training output file

output_file_tst - Name of the test output file

input_file_tra - Name of the training file

input_file_tst - Name of the test file

rule_file - Name of the rule file

quality_file - Name of the output quality file

nlabels - Number of labels for the continuous variables
