M = word2vec(emb,words)
returns the embedding vectors of words in the embedding
emb. If a word is not in the embedding vocabulary, then the
function returns a row of NaNs. The function, by default, is case
sensitive.
M = word2vec(emb,words,'IgnoreCase',true)
returns the embedding vectors of words ignoring case using any
of the previous syntaxes. If multiple words in the embedding differ only in case,
then the function returns the vector corresponding to one of them and does not
return any particular vector.
Load a pretrained word embedding using fastTextWordEmbedding. This function requires Text Analytics Toolbox™ Model for fastText English 16 Billion Token Word Embedding support package. If this support package is not installed, then the function provides a download link.
emb = fastTextWordEmbedding
emb =
wordEmbedding with properties:
Dimension: 300
Vocabulary: [1×1000000 string]
Map the words "Italy", "Rome", and "Paris" to vectors using word2vec.
italy = word2vec(emb,"Italy");
rome = word2vec(emb,"Rome");
paris = word2vec(emb,"Paris");
Map the vector italy - rome + paris to a word using vec2word.
Input word embedding, specified as a wordEmbedding object.
words — Input words string vector | character vector | cell array of character vectors
Input words, specified as a string vector, character vector, or cell array of character
vectors. If you specify words as a character vector, then the
function treats the argument as a single word.
