Vector simlarity search algorithms identify similar vectors based on the vector distance between them.

Neptune Analytics supports the following vector-similarity search algorithms:

Note

The following special floating-point values are not supported in Neptune Analytics vector-similarity search algorithms:

• INF  (infinity)

• -INF  (negative infinity)

• NaN  (not-a-number)
