Learning the kernel via convex optimization
Convex optimization kernel methods machine learning support vector machine
2015/8/10
The performance of a kernel-based learning algorithm depends very much on the choice of the kernel. Recently, much attention has been paid to the problem of learning the kernel itself from given train...
Multi-period portfolio optimization with constraints and transaction costs
Investment combinatorial optimization the horizon assets minimum deviation standard dynamic
2015/8/10
We consider the problem of multi-period portfolio optimization over a finite horizon, with a self-financing budget constraint and arbitrary distribution of asset returns, with objective to minimize th...
Cutting-set methods for robust convex optimization with pessimizing oracles
robust optimization cutting-set methods semi-infi nite programming minimax optimization games
2015/8/10
We consider a general worst-case robust convex optimization problem, with arbitrary dependence on the uncertain parameters, which are assumed to lie in some given set of possible values. We describe a...
First order optimization methods often perform poorly on ill-conditioned optimization problems. However, by preconditioning the problem data and solving the preconditioned problem, the performance of ...

Hyperbolicity cones of elementary symmetric polynomials are spectrahedral
hyperbolic polynomials hyperbolicity cones spectrahedral cones elementary symmetric polynomials spanning trees matrix-tree theorem
2012/4/16
We prove that the hyperbolicity cones of elementary symmetric polynomials are spectrahedral, i.e., they are slices of the cone of positive semidefinite matrices. The proof uses the matrix--tree theore...
Based on a description of project networks by max-plus algebra and poset, the adjacency of critical paths is presented using tropical geometry.
Modelling and Control of Blowing-Venting Operations in Manned Submarines
Ballast tanks manned submarines blowing-venting operations optimal control
2011/8/24
Abstract: Motivated by the study of the potential use of blowing and venting operations of ballast tanks in manned submarines as an alternative control system for manoeuvring, we first propose a mathe...
We propose a rigorous framework for Uncertainty Quantification (UQ) in which the UQ objectives and the assumptions/information set are brought to the forefront.

Optimal transport for multifractal random measures. Applications
Random measures multifractal processes optimal transport metric KPZ
2010/11/26
In this paper, we study optimal transportation problems for multifractal random measures. Since these measures are much less regular than optimal transportation theory requires, we introduce a new not...
On the Optimality of Successive Decoding in Compress-and-Forward Relay Schemes
Optimality of Successive Decoding Compress-and-Forward Relay Schemes
2010/12/14
In the classical compress-and-forward relay scheme developed by (Cover and El Gamal, 1979), the decoding process operates in a successive way: the destination first decodes the compressed observation ...
Optimal streaks in a Falkner-Skan boundary layer
Optimal streaks Falkner-Skan boundary layer
2010/12/15
This paper deals with the optimal streaky perturbations (which maximize the perturbed
energy growth) in a wedge flow boundary layer. These three dimensional perturbations are governed by a system of ...
