Abstract : What are the performance guarantees of the algorithms used in practice for clustering problems? In a paper with Phil Klein and Claire Mathieu, we give the first polynomial-time approximation schemes for the following problems: (1) uniform facility location in edge-weighted planar graphs; (2) $k$-median and $k$-means in edge-weighted planar graphs; (3) $k$-means in …
