Fields

Name Description
CosineDistance

Cosine Distance. Defined as 1 - cosine similarity.

We strongly suggest using DOT_PRODUCT_DISTANCE + UNIT_L2_NORM instead of COSINE distance. Our algorithms have been more optimized for DOT_PRODUCT distance which, when combined with UNIT_L2_NORM, is mathematically equivalent to COSINE distance and results in the same ranking.
DotProductDistance

Dot Product Distance. Defined as a negative of the dot product.
SquaredL2Distance

Euclidean (L_2) Distance.
Unspecified

Should not be set.
