Methods

Load(Stream, out Sparse<Double>[], out Boolean[], SerializerCompression)

Loads an array of sparse samples from a stream.

Declaration

public static void Load(Stream stream, out Sparse<double>[] samples, out bool[] outputs, SerializerCompression compression = SerializerCompression.None)

Parameters

Type	Name	Description
System.IO.Stream	stream	The stream from where the file will be loaded.
Sparse<System.Double>[]	samples	The samples that have been read from the file.
System.Boolean[]	outputs	The output labels associated with each sample in samples.
SerializerCompression	compression	The type of compression to use. Default is None.

Load(String, out Sparse<Double>[], out Boolean[], SerializerCompression)

Loads an array of sparse samples from a file in the disk.

Declaration

public static void Load(string path, out Sparse<double>[] samples, out bool[] outputs, SerializerCompression compression = SerializerCompression.None)

Parameters

Type	Name	Description
System.String	path	The path to the file containing the samples to be loaded.
Sparse<System.Double>[]	samples	The samples that have been read from the file.
System.Boolean[]	outputs	The output labels associated with each sample in samples.
SerializerCompression	compression	The type of compression to use. Default is None.

Save(Sparse<Double>[], Boolean[], Stream, SerializerCompression)

Saves an array of sparse samples to a stream.

Declaration

public static void Save(Sparse<double>[] samples, bool[] outputs, Stream stream, SerializerCompression compression = SerializerCompression.None)

Parameters

Type	Name	Description
Sparse<System.Double>[]	samples	The samples that have been read from the file.
System.Boolean[]	outputs	The output labels associated with each sample in samples.
System.IO.Stream	stream	The stream where the file will be saved.
SerializerCompression	compression	The type of compression to use. Default is None.

Save(Sparse<Double>[], Boolean[], String, SerializerCompression)

Saves an array of sparse samples to a file in the disk.

Declaration

public static void Save(Sparse<double>[] samples, bool[] outputs, string path, SerializerCompression compression = SerializerCompression.None)

Parameters

Type	Name	Description
Sparse<System.Double>[]	samples	The samples that have been read from the file.
System.Boolean[]	outputs	The output labels associated with each sample in samples.
System.String	path	The disk path under which the file will be saved.
SerializerCompression	compression	The type of compression to use. Default is None.

Save(Double[][], Boolean[], Stream, SerializerCompression)
