Title: USER LEVEL AUTOMATIC SEGMENTATION METHOD AND SYSTEM
Abstract:
The present invention relates to the technical field of data mining; a user level automatic segmentation method and system. Said method comprises: selecting original sample data; selecting at least one user feature to act as a dimension for calculating distance; determining a number K of classifications; randomly picking K number of users from the original sample data to act as initial class centers; measuring the distance of each remaining user in the original sample data to each current class center, and sorting each remaining user to the nearest class, thereby completing segmentation of K number of classes; recalculating the class centers of each class; repeating the iteration of S5 and S6 until the new class centers are equivalent to the original class centers or stopping iterative operations when the degree of variation is less than a specified threshold, and the currently segmented K number of classifications are considered the user level classifications which need to be segmented. The method may achieve user level automatic segmentation which is accurate, efficient, and which saves on labor costs.
