Name | Description |
COSINE |
Compares vectors based on the angle between them, which allows you to measure similarity that isn't based on the vectors magnitude. We recommend using DOT_PRODUCT with unit normalized vectors instead of COSINE distance, which is mathematically equivalent with better performance. See Cosine Similarity to learn more. |
COSINE_VALUE |
Compares vectors based on the angle between them, which allows you to measure similarity that isn't based on the vectors magnitude. We recommend using DOT_PRODUCT with unit normalized vectors instead of COSINE distance, which is mathematically equivalent with better performance. See Cosine Similarity to learn more. |
DISTANCE_MEASURE_UNSPECIFIED |
Should not be set. |
DISTANCE_MEASURE_UNSPECIFIED_VALUE |
Should not be set. |
DOT_PRODUCT |
Similar to cosine but is affected by the magnitude of the vectors. See Dot Product to learn more. |
DOT_PRODUCT_VALUE |
Similar to cosine but is affected by the magnitude of the vectors. See Dot Product to learn more. |
EUCLIDEAN |
Measures the EUCLIDEAN distance between the vectors. See Euclidean to learn more |
EUCLIDEAN_VALUE |
Measures the EUCLIDEAN distance between the vectors. See Euclidean to learn more |
