Central axes and peripheral points in high dimensional directional datasets.

, 2015
International audienceWe introduce a new notion of central axis for a finite set {a 1 ,. .. , a m } of vectors in R n. In tandem, we discuss different ways of measuring the dispersion of the data points a i 's around the central axis. Finally, we explain

A PVT-Type Algorithm for Minimizing a Nonsmooth Convex Function [PDF]

, 2003
2000 Mathematics Subject Classification: 90C25, 68W10, 49M37.A general framework of the (parallel variable transformation) PVT-type algorithm, called the PVT-MYR algorithm, for minimizing a non-smooth convex function is proposed, via the Moreau-Yosida ...

Finding a Strict Feasible Dual Initial Solution for Quadratic Semidefinite Programming

, 2012
In this paper, we propose an algorithm to comput the dual initial feasible solution for solving a primal-dual optimization problem (convex quadratic semidefinite programming) by a interior point methods.
