Smaller coresets for k-median and k-means clustering
In this paper, we show that there exists a (k, ε)-coreset for k-median and k-means clustering of n points in IRd , which is of size independent of n. In particular, we construct ...

Existence and Stability of Periodic orbits of Periodic Difference Equations with Delays
In this paper, we investigate the existence and stability of periodic orbits of the p-periodic difference equation with delays xn = f(n - 1, xn-k). We show that the periodic orbit...

A 2.5-Factor Approximation Algorithm for the k-MST Problem
The k-MST problem requires finding that subset of at least k vertices of a given graph whose Minimum Spanning Tree has least weight amongst all subsets of at least k vertices. Th...

Privacy-Preserving k-NN for Small and Large Data Sets
It is not surprising that there is strong interest in kNN queries to enable clustering, classification and outlierdetection tasks. However, previous approaches to privacypreservi...
