C# Class Encog.ML.Data.Buffer.BufferedMLDataSet

This class is not memory based, so very long files can be used, without running out of memory. This dataset uses a Encog binary training file as a buffer. When used with a slower access dataset, such as CSV, XML or SQL, where parsing must occur, this dataset can be used to load from the slower dataset and train at much higher speeds. If you are going to create a binary file, by using the add methods, you must call beginLoad to cause Encog to open an output file. Once the data has been loaded, call endLoad. You can also use the BinaryDataLoader class, with a CODEC, to load many other popular external formats. The binary files produced by this class are in the Encog binary training format, and can be used with any Encog platform. Encog binary files are stored using "little endian" numbers.

Public Methods

Method	Description
Add ( IMLData data1 ) : void	Add only input data, for an unsupervised dataset.
Add ( IMLData inputData, IMLData idealData ) : void	Add both the input and ideal data.
Add ( IMLDataPair pair ) : void	Add a data pair of both input and ideal data.
BeginLoad ( int inputSize, int idealSize ) : void	Begin loading to the binary file. After calling this method the add methods may be called.
BufferedMLDataSet ( String binaryFile ) : System	Construct a buffered dataset using the specified file.
Close ( ) : void	Close the dataset.
EndLoad ( ) : void	This method should be called once all the data has been loaded. The underlying file will be closed. The binary fill will then be opened for reading.
GetEnumerator ( ) : IEnumerator	Create an enumerator.
GetRecord ( long index, IMLDataPair pair ) : void	Read an individual record.
Load ( IMLDataSet training ) : void	Load the specified training set.
LoadToMemory ( ) : IMLDataSet	Load the binary dataset to memory. Memory access is faster.

Method Details

Add() public method

Add only input data, for an unsupervised dataset.

public Add ( IMLData data1 ) : void
data1	IMLData	The data to be added.
return	void

Add() public method

Add both the input and ideal data.

public Add ( IMLData inputData, IMLData idealData ) : void
inputData	IMLData	The input data.
idealData	IMLData	The ideal data.
return	void

Add() public method

Add a data pair of both input and ideal data.

public Add ( IMLDataPair pair ) : void
pair	IMLDataPair	The pair to add.
return	void

BeginLoad() public method

Begin loading to the binary file. After calling this method the add methods may be called.

public BeginLoad ( int inputSize, int idealSize ) : void

idealSize	int	The ideal size.
return	void

BufferedMLDataSet() public method

Construct a buffered dataset using the specified file.

pair	IMLDataPair	The data to read.
return	void

Load() public method

Load the specified training set.

public Load ( IMLDataSet training ) : void
training	IMLDataSet	The training set to load.
