embzero

embzero, function

def autodiff pure embzero(): embedding

Returns the default embedding value used by Envision.

Example

table T = with
  [| as Label |]
  [| "default" |]

T.E = embzero()

show table "embzero()" with
  T.Label
  foldAdd(T.E) as "Coordinate sum"
  dot(T.E, T.E) as "Dot"
  similarity(T.E, T.E) as "Similarity"

Remarks

embzero() is the default value used by Envision when an embedding result needs an explicit fallback, for example with sum(T.E) default embzero().
