---|---|
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. |
