Distance matrices are a really useful tool that store pairwise information about how observations from a dataset relate to one another. Here, we will briefly go over how to implement a function in python that can be used to efficiently compute the pairwise distances for a set (s) of vectors.
Books and survey papers containing a treatment of Euclidean distance matrices in-clude, for example, [31, 44, 87], and most recently [3]. The topic of rank mini-mization for Euclidean distance matrix problems is discussed in, for example, [34, 35, 55, 56, 99, 100].
10 wrz 2009 · For example, to compute the Euclidean distances between every pair of points in a collection, distance.cdist(a, a) does the job. Since the distance from a point to itself is 0, the diagonals of this matrix will be all zero.
22 gru 2011 · Given a partially specified symmetric matrix A with zero diagonal, the Euclidean distance matrix completion problem (EDMCP) is to determine the unspecified entries to make A an EDM. We survey three different approaches to solving the EDMCP.
There are two fundamental problems associated with distance geometry [10]: 1) given a matrix, determine whether it is an EDM and 2) given a possibly incomplete set of distances, determine whether there exists a configuration of points in a given embed-ding dimension—the dimension of the smallest affine space com-
Given a partially-specified symmetric matrix A with zero diagonal, the Euclidean distance matrix completion problem (EDMCP) is to determine the unspecified entries to make A a Euclidean distance matrix. We survey three different approaches to solving the EDMCP.
