Sample Based Algorithm for k-Spatial Medians Clustering
Seo Hoon Jin, Byoung Cheol Jung · Korean Journal of Applied Statistics · 2010
As an alternative to the k-means clustering the k-spatial medians clustering has many good points because of advantages of spatial median. However, it has not been used a lot since it needs heavy computation. If the number of objects and the number of variables are large the computation time problem is getting serious. In this study we propose fast algorithm for the k-spatial medians clustering. Practical applicability of the algorithm is shown with some numerical studies.
