Similarity score

Supported in: Batch

Returns the similarity score of two embedding vectors.

Expression categories: Numeric

Declared arguments

  Expression<T>
• Similarity metric - The similarity metric for comparing the left and right embeddings.
  Enum<Cosine Similarity, Dot Product, Euclidean Distance>

Type variable bounds: T accepts Embedded vector

Output type: Double
