DROP3PSO

public DROP3PSO(java.lang.String ficheroScript)

Builder. Creates the basic structures of the algorithm

Parameters:

ficheroScript - Configuration script

Method Detail

readPrototypeSet

public static PrototypeSet readPrototypeSet(java.lang.String nameOfFile)

Reads the prototype set from a data file.

Parameters:

nameOfFile - Name of data file to be read.

Returns:

PrototypeSet built with the data of the file.

_1nn

public static Prototype _1nn(Prototype current,
                             PrototypeSet dataSet)

Implements the 1NN algorithm

Parameters:

current - Prototype which the algorithm will find its nearest-neighbor.

dataSet - Prototype set in which the algorithm will search.

Returns:

Nearest prototype to current in the prototype set dataset.

classficationAccuracy1NN

public double classficationAccuracy1NN(PrototypeSet training,
                                       PrototypeSet test)

Computes the accuracy for the given test dataset with the 1NN algorithm.

Parameters:

training - training dataset for the 1NN.

test - Test dataset to compute its accuracy.

Returns:

the accuracy for the given test dataset.

reduceSet

public PrototypeSet reduceSet(PrototypeSet initial)

Generate a reduced prototype set by the PSOGenerator method.

Returns:

Reduced set by PSOGenerator's method.

ejecutar

public void ejecutar()

leerConfiguracion

public void leerConfiguracion(java.lang.String ficheroScript)

Description copied from class: Metodo

Reads the parameters of the algorithm. Must be implemented in the subclass.

Overrides:

leerConfiguracion in class Metodo

Parameters:

ficheroScript - Configuration script
