Titel: Generalized K-medians. (Examensarbete)
Sammanfattning: K-medians is a popular method for clustering data. We here explore the extension of this method, the generalized K-medians, which allows nonlinear boundaries between neighbouring clusters. We show that it performs equally well or better than the K-medians. Its superiority becomes clear when size and variability differ between clusters.
