WebMar 18, 2024 · 基于网格的 K -means聚类算法步骤如下: 1) 将数据样本点映射到网格中, 取得每个网格的质心点和每个网格的密度; 2) 选取最小质心网格并进行网格划分; 3) 根据选取的聚类初始中心点, 计算每个网格质心到聚 … WebApr 6, 2024 · STING - A Statistical Information Grid Approach STING was proposed by Wang, Yang, and Muntz (VLDB’97). In this method, the spatial area is divided into rectangular cells. There are several levels of cells corresponding to different levels of resolution. For each cell, the high level is partitioned into several smaller cells in the next lower level.
