Matrix Convex Sets Without Absolute Extreme Points [PDF]
Linear Algebra Appl. Vol 537 (2018) pp. 287-301, 2017 This article shows the existence of a class of closed bounded matrix convex sets which do not have absolute extreme points. The sets we consider are noncommutative sets, $K_X$, formed by taking matrix convex combinations of a single tuple $X$. In the case that $X$ is a tuple of compact operators with no nontrivial finite dimensional reducing subspaces,

Extreme-Point Symmetric Mode Decomposition Method for Data Analysis [PDF]
, 2013 An extreme-point symmetric mode decomposition (ESMD) method is proposed to improve the Hilbert-Huang Transform (HHT) through the following prospects: (1) The sifting process is implemented by the aid of 1, 2, 3 or more inner interpolating curves, which ...

Extreme points of the set of density matrices with positive partial transpose [PDF]
Phys. Rev. A 76, 034304 (2007), 2007 We present a necessary and sufficient condition for a finite dimensional density matrix to be an extreme point of the convex set of density matrices with positive partial transpose with respect to a subsystem. We also give an algorithm for finding such extreme points and illustrate this by some examples.

Scalable Surface Reconstruction from Point Clouds with Extreme Scale and Density Diversity [PDF]
, 2017 In this paper we present a scalable approach for robustly computing a 3D surface mesh from multi-scale multi-view stereo point clouds that can handle extreme jumps of point density (in our experiments three orders of magnitude).

Extreme change-point detection [PDF]
We examine rules for predicting whether a point in $\mathbb{R}$ generated from a 50-50 mixture of two different probability distributions came from one distribution or the other, given limited (or no) information on the two distributions, and, as clues ...
