TextEmbedderOptions

class TextEmbedderOptions : TaskOptions, NSCopying

Options for setting up a MPPTextEmbedder.

• l2Normalize

  @brief Sets whether L2 normalization should be performed on the returned embeddings. Use this option only if the model does not already contain a native L2_NORMALIZATION TF Lite Op. In most cases, this is already the case and L2 norm is thus achieved through TF Lite inference.

  NO by default.

  Declaration

  Swift

  var l2Normalize: Bool { get set }

• quantize

  @brief Sets whether the returned embedding should be quantized to bytes via scalar quantization. Embeddings are implicitly assumed to be unit-norm and therefore any dimensions is guaranteed to have value in [-1.0, 1.0]. Use the l2Normalize property if this is not the case.

  NO by default.

  Declaration

  Swift

  var quantize: Bool { get set }
