论文摘要
我们提供了对K-均值的简单分析|| (Bahmani等,PVLDB 2012) - K-Means ++算法的分布式变体(Arthur和Vassilvitskii,Soda 2007)。此外,回合数量的界限从$ O(\ log n)$提高到$ O(\ log n / \ log \ log \ log n)$,我们表明这很紧。
We present a simple analysis of k-means|| (Bahmani et al., PVLDB 2012) -- a distributed variant of the k-means++ algorithm (Arthur and Vassilvitskii, SODA 2007). Moreover, the bound on the number of rounds is improved from $O(\log n)$ to $O(\log n / \log\log n)$, which we show to be tight.
