writeWordEmbedding — Write a word embedding model to a UTF-8 word2vec text file.
writeWordEmbedding(emb, filename) writes a wordEmbedding object to a UTF-8 text file in word2vec text format.
Syntax
writeWordEmbedding(emb, filename)Inputs
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
emb | Any | Yes | — | wordEmbedding object. |
filename | Any | Yes | — | Target UTF-8 word2vec text file. |
Errors
| Identifier | When | Message |
|---|---|---|
RunMat:writeWordEmbedding:InvalidInput | Inputs do not match the supported writeWordEmbedding form. | writeWordEmbedding received invalid input |
RunMat:writeWordEmbedding:IOError | The requested word embedding file cannot be written. | Unable to write word embedding file |
How writeWordEmbedding works
embmust be awordEmbeddingobject withDimension,Vocabulary, and vector storage created byreadWordEmbedding,trainWordEmbedding, orfastTextWordEmbedding.filenamemay be a string scalar, character vector, or a 1-by-1 cell array containing a character vector.- The output file starts with a
numWords dimensionheader followed by one row per vocabulary word and its vector values. - The target file is created or overwritten. Parent directories must already exist.
- Vocabulary entries containing whitespace and non-finite vector values are rejected because word2vec text rows cannot represent them unambiguously.
- Binary word2vec output, zip output, append mode, and format-selection options are not part of the compatibility target's documented
writeWordEmbeddingsyntax and are not accepted. - The filename must be host text. Native integer and resident numeric filename values are rejected before provider or filesystem access.
GPU memory and residency
writeWordEmbedding is a host file-I/O sink and does not launch provider kernels. Resident numeric filename inputs are rejected rather than gathered because they are not valid paths.
Examples
Write a trained embedding
documents = tokenizedDocument(["red blue red"; "green blue"]);
emb = trainWordEmbedding(documents, 'Dimension', 8, 'MinCount', 1);
writeWordEmbedding(emb, "colors.vec")Expected output:
`colors.vec` contains UTF-8 word2vec text embedding data.Round-trip an embedding file
writeWordEmbedding(emb, "model.vec");
copy = readWordEmbedding("model.vec");
copy.DimensionExpected output:
`copy` is a `wordEmbedding` object with the same vocabulary and vectors.Using writeWordEmbedding with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how writeWordEmbedding changes the result.
Run a small writeWordEmbedding example, explain the result, then change one input and compare the output.
FAQ
What file format does writeWordEmbedding use?⌄
It writes UTF-8 word2vec text format with a header row and one word-vector row per vocabulary entry.
Does writeWordEmbedding create folders?⌄
No. Create the parent folder first with mkdir if needed.
Does writeWordEmbedding execute on the GPU?⌄
No. It is host object serialization and file I/O.
