Syntax

Methods

HashingTrick(String, Int32, String, String, Boolean, String)

Declaration

public static int[] HashingTrick(string text, int n, string hash_function = "", string filters = "!\"#$%&()*+,-./:;<=>?@[\\]^_`{|}~\t\n", bool lower = true, string split = " ")

Parameters

Type	Name	Description
System.String	text
System.Int32	n
System.String	hash_function
System.String	filters
System.Boolean	lower
System.String	split

Returns

Type	Description
System.Int32[]

OneHot(String, Int32, String, Boolean, String)

One-hot encodes a text into a list of word indexes of size n. This is a wrapper to the hashing_trick function using hash as the hashing function; unicity of word to index mapping non-guaranteed.

Declaration

public static int[, ] OneHot(string text, int n, string filters = "!\"#$%&()*+,-./:;<=>?@[\\]^_`{|}~\t\n", bool lower = true, string split = " ")

Parameters

Type	Name	Description
System.String	text	The text.
System.Int32	n	The n.
System.String	filters	The filters.
System.Boolean	lower	if set to true [lower].
System.String	split	The split.

Returns

Type	Description
System.Int32[,]

TextToWordSequence(String, String, Boolean, String)

Texts to word sequence.

Declaration

public static string[] TextToWordSequence(string text, string filters = "!\"#$%&()*+,-./:;<=>?@[\\]^_`{|}~\t\n", bool lower = true, string split = " ")

Parameters

Type	Name	Description
System.String	text	The text.
System.String	filters	The filters.
System.Boolean	lower	if set to true [lower].
System.String	split	The split.

Returns

Type	Description
System.String[]
