dot

dot, function

def autodiff pure dot(x: embedding, y: embedding): number

Returns the dot product of the embeddings x and y.

• x: the first embedding.
• y: the second embedding.

Example

table T = with
  [| as Group |]
  [| "A" |]
  [| "B" |]
  [| "B" |]

T.E = embzero()

show table "Embedding dot product" with
  T.Group
  dot(sum(T.E) default embzero(), embzero()) as "Dot"
  group by T.Group

This outputs the following table:

Remarks

dot is available inside autodiff blocks.
