English(EN) Faster and Simpler Greedy Algorithm for $k$-Median and $k$-Means

新的贪心算法简化了 $k$-中值和 $k$-均值聚类

作者 PulseAugur 编辑部 · [1 个来源] · 2026-07-09 04:00

研究人员开发了一种更简单、更快的贪心算法，用于解决 $k$-均值和 $k$-中值聚类问题。这种新方法改进了 Mettu 和 Plaxton 的递归贪心算法，在图指标和欧几里得空间中提供了更优的性能。该算法的实现得到了简化，使其在无监督学习的实际应用中更加高效。 AI

影响为无监督学习任务提供了一种更有效的算法方法。

更快速、更简单的 $k$-Median 和 $k$-Means 贪心算法

arXiv:2407.11217v4 Announce Type: replace-cross Abstract: Clustering problems such as $k$-means and $k$-median are staples of unsupervised learning, and many algorithmic techniques have been developed to tackle their numerous aspects. In this paper, we focus on the class of greed…
