Abstract
A method for querying in a candidate vector set candidate vectors similar to object vectors is disclosed, wherein the candidate vector set comprises a plurality of candidate vectors each being quantized as having a central vector portion and a residual vector portion, the method comprising: querying, a first number of candidate vector subsets that are closest to the object vector; generating and storing a plurality of common calculation results based on a set of central vector portions and a set of residual vector portions of candidate vectors of the first number of candidate vector subsets; generating and storing pre-calculation results based on the set of object vectors and the set of residual vector portion; and determining, a second number of candidate vectors that are similar to each object vector in the corresponding first number of candidate vector subsets based on the stored pre-calculation results and common calculation results.
