<SerializableAttribute>
Public Class RCV1v2
	Inherits SparseDataSet

The RCV1v2 type exposes the following members.

Constructors

	Name	Description
	RCV1v2	Downloads and prepares the RCV1-v2 dataset.

Properties

	Name	Description
	Classes	Gets the document class labels in this dataset.
	ClassLabelToDocument	Gets a mapping giving a list of all document labels that have been labelled with a given class label.
	Documents	Gets a mapping of a document identifier and all the words it contains.
	DocumentToClassLabel	Gets a mapping giving a list of all class labels that a document has been labelled with.
	Path	Gets the path to the directory where the datasets will be stored. (Inherited from WebDataSet.)
	Testing	Gets the testiong set of the RCV1-v2 dataset.
	Training	Gets the training set of the RCV1-v2 dataset.

Methods

	Name	Description
	Download	Downloads the dataset from a specified URL, saving it to disk, and returning it as a set of sparse vectors>. If the dataset already exists in the disk, it will not be redownloaded again. (Inherited from SparseDataSet.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Extension Methods

	Name	Description
	HasMethod	Checks whether an object implements a method with the given name. (Defined by ExtensionMethods.)
	IsEqual	Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices. (Defined by Matrix.)
	To(Type)	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)
	ToT	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)
