Abstract

The embodiment of the invention discloses an incremental clustering method and device, an electronic device and a computer readable medium. An embodiment of the method comprises the following steps ofclustering an original data set by utilizing a density-based clustering algorithm with noise, and determining a cluster in the original data set; and in response to detected update of the original data set, performing incremental clustering on a new data set obtained through updating based on the update type of the original data set so as to update the cluster in the original data set. Accordingto the embodiment, the clustering efficiency is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, specifically an incremental clustering method, device, electronic equipment, and computer-readable media. Background technique [0002] With the development of computer technology and Internet technology, in many application scenarios, data sets need to be clustered. For example, in the application scenarios of face detection or face recognition, face clustering is usually required. In such an application scenario, the data set is usually updated continuously, new objects (that is, new data) are continuously added, and old objects are deleted. [0003] There are currently few incremental clustering methods. When the data set changes, the full clustering method is usually used to re-cluster the objects in the updated data set. In this way, every time the data set is updated, the updated data set needs to be regarded as a new data set, and information such as distan...
