Problems solved by technology

[0004] The above technology still has good performance when the amount of data is on the order of millions, but when the dimension of users and items reaches the level of 100 million, even if there is a large-scale computing cluster, the computing cost is very high, resulting in relatively poor computing performance

Abstract

The invention discloses a neighbor vector recalling method and device, computer equipment and a storage medium, and relates to the field of cloud conferences. The method comprises the steps that clustering results of a source vector set and a target vector set are acquired, and the clustering results comprise at least two types of clustering vector sets and centroid vectors of the clustering vector sets; determining at least one neighbor vector set of the source vector from the clustering vector set according to a first similarity between the source vector and the centroid vector of the clustering vector set; and recalling a target neighbor vector from the candidate neighbor vectors according to the second similarity between the source vector and each candidate neighbor vector in the neighbor vector set.

Description

technical field [0001] The embodiments of the present application relate to the field of information push, and in particular to a neighbor vector recall method, device, computer equipment and storage medium. Background technique [0002] Neighbor vector recall is a technique for recommending information that may be of interest to users based on the similarity between their user profile and item dimensions. [0003] In related technologies, when recommending a certain user A, the server calculates the first vector of the user and the second vector of the item, and calculates the similarity between the first vector and the second vector. The second vector is sorted in descending order of similarity with the first vector, and the recommendation information of the user A is generated according to the items corresponding to the top k ranked second vectors. [0004] The above technologies still have good performance when the amount of data is on the order of millions, but when th...
