Embedding

class Embedding : NSObject

Represents the embedding for a given embedder head. Typically used in embedding tasks.

One and only one of the two ‘floatEmbedding’ and ‘quantizedEmbedding’ will contain data, based on whether or not the embedder was configured to perform scala quantization.

• floatEmbedding

  @brief The embedding represented as an NSArray of Float values. Empty if the embedder was configured to perform scalar quantization.

  Declaration

  Swift

  var floatEmbedding: [NSNumber]? { get }

• quantizedEmbedding

  @brief The embedding represented as an NSArray of UInt8 values. Empty if the embedder was not configured to perform scalar quantization.

  Declaration

  Swift

  var quantizedEmbedding: [NSNumber]? { get }

• headIndex

  The index of the embedder head these entries refer to. This is useful for multi-head models.

  Declaration

  Swift

  var headIndex: Int { get }

• headName

  The optional name of the embedder head, which is the corresponding tensor metadata name.

  Declaration

  Swift

  var headName: String? { get }

• init(floatEmbedding:quantizedEmbedding:head:headName:)

  Initializes a new MPPEmbedding with the given float embedding, quantized embedding, head index and head name.

  Declaration

  Swift

  init(floatEmbedding: [NSNumber]?, quantizedEmbedding: [NSNumber]?, head headIndex: Int, headName: String?)

  Parameters

  floatEmbedding	The optional Floating-point embedding.
  quantizedEmbedding	The optional Quantized embedding.
  headIndex	The index of the embedder head.
  headName	The optional name of the embedder head.

  Return Value

  An instance of MPPEmbedding initialized with the given float embedding, quantized embedding, head index and head name.
