WebMar 6, 2024 · 为了改善K-Means算法的聚类效果,可以采用改进的距离度量方法,例如使用更加适合数据集的Minkowski距离;另外,可以引入核技巧来改善K-Means算法的聚类精度。为了改善K-Means算法的收敛速度,可以采用增量K-Means算法,它可以有效的减少K-Means算法的运行时间。 WebBisecting k-means. Bisecting k-means is a kind of hierarchical clustering using a divisive (or “top-down”) approach: all observations start in one cluster, and splits are performed recursively as one moves down the hierarchy.. Bisecting K-means can often be much faster than regular K-means, but it will generally produce a different clustering.
