Méthode	Description
Add ( string label ) : void	Adds a labeled vector to the vocabulary, assigning a default (random) value to the vector.
Add ( string label, float vector ) : void	Adds a labeled vector to the vocabulary.
FindNearestNeighbors ( LabeledVector vector, int neighborhoodSize ) : LabeledVector>>.List	Finds the vectors most similar to the input vector. If the input is the zero vector, an empty list is returned.
FindNearestNeighbors ( float vector, int neighborhoodSize ) : LabeledVector>>.List	Finds the vectors most similar to the input vector. If the input is the zero vector, an empty list is returned.
IsZero ( float vector ) : bool	Returns true if the argument is the zero vector.
Read ( StreamReader vocabularyReader ) : void	Loads the vocabulary from text using a StreamReader
ReadTextFile ( string path ) : void	Loads the vocabulary from a file in text format (e.g., word2vec)
VectorFromLabel ( string label ) : float[]	Retrieves the vector that corresponds to a label.
Vocabulary ( int vectorDimensions, WordVectorType vectorType = WordVectorType.Random ) : System	Constructs the Vocabulary.

Méthode	Description
GetOOVVector ( string label ) : float[]	Returns a new vector for an out-of-vocabulary word.
MakeNewVector ( ) : float[]	Creates a new vector.
MakeOneOfNVector ( ) : float[]	Creates a new one-of-N vector.
MakeRandomVector ( ) : float[]	Creates a random vector uniformly distributed over the vector space. Components are in [0, 1[.
ReadFileHeader ( StreamReader vocabularyReader ) : void	Reads the first part of a text file. The header consists of a single line with one or two fields: [number_of_vectors] number_of_dimensions The word2vec text format uses both fields.
ReadLabeledVectors ( StreamReader vocabularyReader ) : void	Reads labeled vectors from a text file.
ReadLineFields ( StreamReader vocabularyReader ) : string[]	Reads a line and splits it on whitespace into fields.

Adds a labeled vector to the vocabulary, assigning a default (random) value to the vector.

Adds a labeled vector to the vocabulary.

public Add ( string label, float vector ) : void
label	string	The label
vector	float	The vector
Résultat	void

Finds the vectors most similar to the input vector. If the input is the zero vector, an empty list is returned.

public FindNearestNeighbors ( LabeledVector vector, int neighborhoodSize ) : LabeledVector>>.List
vector	LabeledVector	The input vector
neighborhoodSize	int	The number of neighbors to retrieve
Résultat	LabeledVector>>.List

Finds the vectors most similar to the input vector. If the input is the zero vector, an empty list is returned.

public FindNearestNeighbors ( float vector, int neighborhoodSize ) : LabeledVector>>.List
vector	float	The input vector
neighborhoodSize	int	The number of neighbors to retrieve
Résultat	LabeledVector>>.List

Returns true if the argument is the zero vector.

public static IsZero ( float vector ) : bool
vector	float	The input vector
Résultat	bool

Loads the vocabulary from text using a StreamReader

public Read ( StreamReader vocabularyReader ) : void
vocabularyReader	System.IO.StreamReader	The reader
Résultat	void

Loads the vocabulary from a file in text format (e.g., word2vec)

public ReadTextFile ( string path ) : void
path	string	The path to the vocabulary text file
Résultat	void

Retrieves the vector that corresponds to a label.

public VectorFromLabel ( string label ) : float[]
label	string	The label to look up
Résultat	float[]

Constructs the Vocabulary.

public Vocabulary ( int vectorDimensions, WordVectorType vectorType = WordVectorType.Random ) : System
vectorDimensions	int	The number of word vector dimensions
vectorType	WordVectorType	The vector type used
Résultat	System
