Abstract

The invention discloses a vector information retrieval method. The method comprises the steps of obtaining a first target vector; obtaining a first matching vector cluster matched with the first target vector; and obtaining first matching vector information matched with the first target vector according to the first matching vector cluster. According to the method, the calculation efficiency during vector retrieval is improved, and the problems of high memory access complexity and unstable performance during vector retrieval are solved.

Description

technical field [0001] This application relates to the field of vector retrieval, in particular to a vector information retrieval method and system. The present application also relates to a field programmable gate array and an information retrieval method. Background technique [0002] With the advent of the era of big data, after vectorizing text, graphics, images, audio, video and other objects, it is widely used to find similar objects through correlation vector retrieval algorithms, such as face recognition, similar image retrieval, related video retrieval, etc. [0003] However, after vectorizing objects such as graphics and images, with the increase of vector dimensions and the continuous increase of retrieval resources in related retrieval databases, when dealing with specific vector retrieval, the amount of data calculation involved is usually large, and the computational complexity Higher, the output of the final result is slower. Therefore, how to increase the s...
