Static Fields

Name Description
COSINE_DISTANCE

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.

COSINE_DISTANCE = 2;

COSINE_DISTANCE_VALUE

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.

COSINE_DISTANCE = 2;

DISTANCE_MEASURE_TYPE_UNSPECIFIED

Should not be set.

DISTANCE_MEASURE_TYPE_UNSPECIFIED = 0;

DISTANCE_MEASURE_TYPE_UNSPECIFIED_VALUE

Should not be set.

DISTANCE_MEASURE_TYPE_UNSPECIFIED = 0;

DOT_PRODUCT_DISTANCE

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

DOT_PRODUCT_DISTANCE = 3;

DOT_PRODUCT_DISTANCE_VALUE

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

DOT_PRODUCT_DISTANCE = 3;

SQUARED_L2_DISTANCE

Euclidean (L_2) Distance.

SQUARED_L2_DISTANCE = 1;

SQUARED_L2_DISTANCE_VALUE

Euclidean (L_2) Distance.

SQUARED_L2_DISTANCE = 1;
