Distance matrix completions

V delu diplomskega seminarja obravnavamo problem razdaljnih matričnih napolnitev. Naš cilj je iz delno napolnjene matrike s podatki o razdaljah med točkami določiti vse razdalje oz. neznane elemente.

Distance Matrix Completion by Numerical Optimization

, 1997
Consider the problem of determining whether or not a partial dissimilarity matrix can be completed to a Euclidean distance matrix. The dimension of the distance matrix may be restricted and the known dissimilarities may be permitted to vary subject to ...

The Distance Matrix for a Simplex

Croatica Chemica Acta, 1995
In this paper we consider some geometric questions relating to a higher dimensional analogon of a triangle, called simplex. In particular, weshall be concerned with the distance matrix of its vertices. We shall also majorize the volume of a simplex in terms of the distances between vertices.

On the geometric interpretation of the nonnegative rank [PDF]

The nonnegative rank of a nonnegative matrix is the minimum number of nonnegative rank-one factors needed to reconstruct it exactly. The problem of determining this rank and computing the corresponding nonnegative factors is difficult; however it has ...
