Class ToBinaryPlugin

java.lang.Object
  org.joone.util.AbstractConverterPlugIn
      org.joone.util.ConverterPlugIn
          org.joone.util.ToBinaryPlugin

All Implemented Interfaces:

java.io.Serializable, PlugInListener

public class ToBinaryPlugin
extends ConverterPlugIn

This plug-in converts 10-base data to binary format. The plug-in ingnores the broken part (the part after the . ) for non-integer numbers. It works correct for positive as well as for negative numbers.

Method Detail

convert

protected boolean convert(int serie)

Description copied from class: AbstractConverterPlugIn

Applies the conversion on the Nth serie of the buffered pattern data. The method is abstract and should be overridden by the implementing class. Implementing classes can obtain the input patterns by calling the AbstractConverterPlugIn.getInputVector() method. The result is a Vector of Pattern objects which this method should use by converting the requested serie.

Specified by:

convert in class AbstractConverterPlugIn

Parameters:

serie - the serie to convert

apply

protected boolean apply()

Description copied from class: AbstractConverterPlugIn

Applies all the conversions on the patterns contained by AbstractConverterPlugIn.InputVector

Overrides:

apply in class AbstractConverterPlugIn

Returns:

true if the input buffer is changed

getBinary

protected double[] getBinary(double aNumber)

Converts a number to a binary number (the part after the . (like 348 in 321.348) is ignored).

Parameters:

aNumber - the number to convert.

Returns:

the converted number as an array in binary form.

setUpperBit

public void setUpperBit(double aValue)

Sets the value for the upper bit. In binary problems it is often better to use 0.3 and 0.7 or -0.7 and 0.7 as target instead of 0 and 1 or -1 and 1, because the asymptotes (0 and 1) tend to take a long time to train, worsen generalization and drive the weights to very large values. By using this function you can set a different value for the upper bit.

Parameters:

aValue - the value to use for the upper bit.

getUpperBit

public double getUpperBit()

Gets the value used for the upper bit.

setLowerBit

public void setLowerBit(double aValue)

Sets the value for the lower bit.

Parameters:

aValue - the value to use for the lower bit.

getLowerBit

public double getLowerBit()

Gets the value used for the lower bit.
