Embodiment Construction

[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0046] It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0047] The present application relates to the technical field of data processing, and in particular, to a classification method, a classification device, a classification device, and a computer-readable storage medium.

[0048] DCPA, an algorithm for density clustering proposed in a paper published in Science in 2014. DCPA is to use the idea that the density of the cluster center point is greater than the density of the surrounding points, and the distance between the cluster center and the higher density center point is larger to cluster the data to be classified. Therefore, when using DCPA to...

Abstract

The invention discloses a classification method. The method comprises the steps of obtaining to-be-classified data; processing the to-be-classified data based on a K-means clustering algorithm to obtain K first-class clusters; wherein K is an integer greater than 1; obtaining a class cluster weight of each class cluster in the K first class clusters; wherein the class cluster weight of each class cluster is used for representing the probability that each class cluster is a clustering center; and based on the class cluster weight of each class cluster, classifying the K first class clusters. The invention further discloses a classification device, equipment and a storage medium. According to the classification method provided by the invention, the classification precision can be improved, and meanwhile, the data operation time complexity and the requirement on the memory of the computing equipment can be reduced.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, to a classification method, a classification device, a classification device, and a computer-readable storage medium. Background technique [0002] When using the Density Peaks Clustering Algorithm (DCPA) to cluster the data set, with the increase of the amount of data at the data level, it is easy to increase the time consumption and the memory consumption of the computing device in the process of using DCPA to process the data. The problem is too large, which can easily affect the speed of data clustering. In order to improve the above defects of DCPA in data clustering, a grid-based density peak clustering method is proposed in the related art, which divides the data set to be classified into disjoint grids of the same size. Each grid unit is calculated as a whole, and then the above calculation results are combined through DCPA to complete the data cluste...
