Method GetEmbeddingsAsync

Namespace

LMKit.Embeddings

Assembly

LM-Kit.NET.dll

GetEmbeddingsAsync(Attachment, CancellationToken)

Asynchronously generates the embedding vector for a given file attachment. If the associated LM supports image embeddings, image attachments (for example, PNG, JPEG, TIFF) will be processed into embeddings; otherwise, text‑based attachments (for example, TXT, HTML) will be used.

public Task<float[]> GetEmbeddingsAsync(Attachment attachment, CancellationToken cancellationToken = default)

Parameters

attachment Attachment

The file attachment containing content, name, MIME type, and size. Supported formats include: PNG, BMP, GIF, PSD, PIC, JPEG, PNM, HDR, TGA, WEBP, TIFF, TXT, HTML.

cancellationToken CancellationToken

Optional. A CancellationToken for handling cancellation requests.

Returns

Task<float[]>

A task that represents the asynchronous operation. The task result contains an array of floats representing the embedding vector of the attachment’s content.

Exceptions

ArgumentNullException

Thrown when attachment is null.

InvalidModelException

Thrown when attachment requires vision processing but the current model does not support image embeddings.

GetEmbeddingsAsync(string, CancellationToken)

Asynchronously generates the embedding vector for a given text string. This vector represents the text in a high-dimensional space, enabling various natural language processing tasks by capturing semantic meaning.

public Task<float[]> GetEmbeddingsAsync(string text, CancellationToken cancellationToken = default)

Parameters

text string

The text string to be converted into an embedding vector. Cannot be null or empty.

cancellationToken CancellationToken

Optional. A CancellationToken for handling cancellation requests.

Returns

Task<float[]>

A task that represents the asynchronous operation. The task result contains an array of floats representing the embedding vector of the input text.

Remarks

The dimension of the array is specified by the EmbeddingSize property.

Exceptions

ArgumentNullException

Thrown when the input text is null or empty.

GetEmbeddingsAsync(IEnumerable<string>, CancellationToken)

Asynchronously generates embedding vectors for a collection of text strings. Each vector represents a text in a high-dimensional space, enabling various natural language processing tasks by capturing semantic meaning.

public Task<float[][]> GetEmbeddingsAsync(IEnumerable<string> text, CancellationToken cancellationToken = default)

Parameters

text IEnumerable<string>

An enumerable of text strings to be converted into embedding vectors. Cannot be null or empty.

cancellationToken CancellationToken

Optional. A CancellationToken for handling cancellation requests.

Returns

Task<float[][]>

A task that represents the asynchronous operation. The task result contains an array of float arrays, each representing the embedding vector of the corresponding input text.

Exceptions

ArgumentNullException

Thrown when the input text is null or empty.

GetEmbeddingsAsync(IList<int>, CancellationToken)

Asynchronously generates the embedding vector for a given tokenized text. This vector represents the text in a high-dimensional space, enabling various natural language processing tasks by capturing semantic meaning.

public Task<float[]> GetEmbeddingsAsync(IList<int> tokens, CancellationToken cancellationToken = default)

Parameters

tokens IList<int>

The list of tokens to be converted into an embedding vector. Cannot be null or empty.

cancellationToken CancellationToken

Optional. A CancellationToken for handling cancellation requests.

Returns

Task<float[]>

A task that represents the asynchronous operation. The task result contains an array of floats representing the embedding vector of the input tokens.

Remarks

The dimension of the array is specified by the EmbeddingSize property.

Exceptions

ArgumentNullException

Thrown when the input tokens are null or empty.

GetEmbeddingsAsync(IEnumerable<IList<int>>, CancellationToken)

Asynchronously generates embedding vectors for a collection of tokenized texts. Each vector represents a text in a high-dimensional space, enabling various natural language processing tasks by capturing semantic meaning.

public Task<float[][]> GetEmbeddingsAsync(IEnumerable<IList<int>> tokens, CancellationToken cancellationToken = default)

Parameters

tokens IEnumerable<IList<int>>

An enumerable of token lists to be converted into embedding vectors. Cannot be null or empty.

cancellationToken CancellationToken

Optional. A CancellationToken for handling cancellation requests.

Returns

Task<float[][]>

A task that represents the asynchronous operation. The task result contains an array of float arrays, each representing the embedding vector of the corresponding input tokens.

Exceptions

ArgumentNullException

Thrown when the input tokens are null or empty.
