smaller coresets for k-median and k-means clustering
In this paper, we show that there exists a (k, ?)-coreset for k-median and k-means clustering of n points in R d , which is of size independent of n. In particular, we construct a (k, ?)-coreset of size O(k 2 /? d ) for k-median clustering, and of size O(k 3 /? d+1 ) for k-means clustering.
