@msokolov the transformation also preserves the inner product up to a query-specific constant. >what is the meaning of the length of the vectors - where does it come from? Do the training processes generate non-unit vectors Yes, the training process often uses the inner/doct product and not the cosine similarity, so some information is being encoded by the vector length/magnitude. Typically, however, the variance isn't that huge. -- This is an automated message from the Apache Git Service.
