Class RandomClassification

java.lang.Object
  extended by marf.Storage.StorageManager
      extended by marf.Classification.Classification
          extended by marf.Classification.RandomClassification.RandomClassification
All Implemented Interfaces:
java.io.Serializable, java.lang.Cloneable, IClassification, IStorageManager

public class RandomClassification
extends Classification

Random Classification Module is for testing purposes.

This represents the bottom-line of the classification results. All the other modules should be better than this 99% of the time. If they are not, debug them.

RandomClassification

public RandomClassification(IFeatureExtraction poFeatureExtraction)
RandomClassification Constructor.

Parameters:
poFeatureExtraction - FeatureExtraction module reference
Method Detail

classify

public final boolean classify(double[] padFeatureVector)
                       throws ClassificationException
Picks an ID at random. In 0.3.0.6 the generic pipelined version of this API classify() was refactored into the Classification.

Parameters:
padFeatureVector - unused
Returns:
true
Throws:
ClassificationException
Since:
0.3.0.6

train

public final boolean train(double[] padFeatureVector)
                    throws ClassificationException
Simply stores incoming ID's to later pick one at random.

Specified by:
train in interface IClassification
Overrides:
train in class Classification
Parameters:
padFeatureVector - unused
Returns:
true if training was successful
Throws:
ClassificationException
Since:
0.3.0.6
See Also:
TrainingSet

dump

public final void dump()
                throws StorageException
Dumps "training set" of IDs.

Specified by:
dump in interface IStorageManager
Overrides:
dump in class Classification
Throws:
StorageException
See Also:
IStorageManager.DUMP_GZIP_BINARY, IStorageManager.DUMP_BINARY, StorageManager.dumpGzipBinary(), StorageManager.dumpCSV(), StorageManager.dumpBinary(), StorageManager.dumpXML(), StorageManager.dumpHTML(), StorageManager.dumpSQL(), StorageManager.backSynchronizeObject(), StorageManager.iCurrentDumpMode

restore

public final void restore()
                   throws StorageException
Restores "training set" of IDs.

Specified by:
restore in interface IStorageManager
Overrides:
restore in class Classification
Throws:
StorageException - if there was an error loading the data file.
See Also:
IStorageManager.DUMP_GZIP_BINARY, IStorageManager.DUMP_BINARY, StorageManager.dumpGzipBinary(), StorageManager.dumpCSV(), StorageManager.dumpBinary(), StorageManager.dumpXML(), StorageManager.dumpHTML(), StorageManager.dumpSQL(), StorageManager.backSynchronizeObject(), StorageManager.iCurrentDumpMode

backSynchronizeObject

public void backSynchronizeObject()
Description copied from class: StorageManager

Overrides:
backSynchronizeObject in class StorageManager
Since:
0.3.0.6
See Also:
StorageManager.backSynchronizeObject()

getResult

public Result getResult()
Retrieves the classification result.

Returns:
Result object
Since:
0.3.0.2

toString

public java.lang.String toString()
Returns string representation of the internals of this object.

Overrides:
toString in class StorageManager
Returns:
String
Since:
0.3.0.1
See Also:
Object.toString()

getMARFSourceCodeRevision

public static java.lang.String getMARFSourceCodeRevision()
Retrieves class' revision.

Returns:
revision string
Since:
0.3.0.2
