Abstract:We present an algorithm for computing ε-coresets for (k, ℓ)-median clustering of polygonal curves in R d under the Fréchet distance. This type of clustering, which has recently drawn increasing popularity due to a growing number of applications, is an adaption of Euclidean k-median clustering: we are given a set of polygonal curves in R d and want to compute k median curves such that the sum of distances from the given curves to their closest median curve is minimal. Additionally, we restrict the complexity, i… Show more
