Abstract

The present invention provides a clustering method and apparatus, a computer device, a storage medium, and a program product. The method comprises: selecting an unclustered sample from a sample set asa candidate sample; building a neighborhood of the candidate sample according to location information of the candidate sample; when both the number of first samples of the sample within the neighborhood and the number of first users of the user to which the sample belongs within the neighborhood exceed the respective thresholds, determining the candidate sample as the core object; iteratively obtaining the density reachable sample of the core object, and using the density reachable sample of each iteration to update the cluster currently corresponding to the core object until the final targetcluster of the core object is obtained; and when there is no unclustered sample in the sample set, completing clustering processing of the sample set, and obtaining all target clusters of the sampleset. The method provided by the present invention can perform clustering processing on the sample set in global, and the applicability of the method can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a clustering method, device, computer equipment, storage medium and program product. Background technique [0002] With the continuous development of Internet technology, according to the historical records of user behavior, it is of great value to discover user preference information, so that personalized and accurate services can be provided to users. In the prior art, clusters are obtained through a statistical method based on a pre-defined rule area, and then active clusters are discovered according to the clusters. [0003] In this way, because the statistical method can only be based on the pre-defined rule area, the applicability is not high, resulting in poor clustering effect. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0005] Therefore, the first purpose ...
