Spatial median (L1 median) In a normed vector space of dimension two or greater, the "spatial median" minimizes the expected distance [Math Processing Error] where X and a are vectors, if this expectation has a finite minimum; another definition is better suited for general probability-distribut...
The definition of the median as a 'middle position' value is not possible here because of the lack of a universally accepted total order in the space of interval data, so the median is defined as the element which minimizes the mean distance, in terms of an L 1 metric (extension of ...
This function is based on some notion of genomic distance, either the number of adjacent elements on a chromosome in one genome that are disrupted in another – the breakpoint distance – or the number of evolutionary operations necessary to transform one genome to another. While the karyotypes...
Results for coreset construction + basic weighted medoid (L1 distance) The size of the coreset was set 0.11 * the number of data points. We asked 10 clusters. We give the cost of clustering the coreset and the cost (of dispatching a posteriori the whole original data to the medoids positio...

In order to recall how this generalization has been done in the literature, the L1 distance based on the ϕ-wabl/ldev/rdev representation and used in such concept will be specified now. Definition 2.2 [16] Given an absolutely continu- ous probability measure ϕ on the measurable space (...
