Matrix distanceDiogo Melo
by any permutation matrix Ξ has null effect on its range. In other words, any permutation of the rows or columns of V N pro- duces a basis for N(1 T ); id est, R(ΞV N ) = R(V N Ξ) = R(V N ) = N(1 T ). Hence, the matrix inequality −V T N DV N ≻ ...

Our goal is to learn a Mahalanobis matrix A such that the distances of point pairs in S are as small as possible, while those in D are as large as possible. According to Eq. (2), equivalently, we can select to optimize the matrix W∈Rn×d, with d⩽n. To this end, we ...
