Several kinds of Stability of efficient Solutions in Vector Trajectorial discrete Optimization Problem [PDF]

, 2005
This work was partially supported by DAAD, Fundamental Researches Foundation of Belarus and International Soros Science Education Program We consider a vector discrete optimization problem on a system of non- empty subsets (trajectories) of a finite set.

Comprehensive review on twin support vector machines [PDF]

Annals of Operations Research, 2021
Twin support vector machine (TWSVM) and twin support vector regression (TSVR) are newly emerging efficient machine learning techniques which offer promising solutions for classification and regression challenges respectively. TWSVM is based upon the idea

Propagation of chaos and Poincar\'e inequalities for a system of particles interacting through their cdf [PDF]

, 2008
In the particular case of a concave flux function, we are interested in the long time behaviour of the nonlinear process associated to the one-dimensional viscous scalar conservation law.

Degenerate abnormal trajectories in a sub-Riemannian problem with growth vector (2, 3, 5, 8) [PDF]

Differential Equations, 2017
We consider the nilpotent sub-Riemannian problem with growth vector (2, 3, 5, 8). We describe and study abnormal extremals orthogonal to the cube of the distribution. We analyze the geometric properties of a two-dimensional surface in the state space on which the corresponding abnormal trajectories define optimal synthesis. © 2017, Pleiades Publishing,

Long-time convergence of an adaptive biasing force method: Variance reduction by Helmholtz projection [PDF]

, 2015
In this paper, we propose an improvement of the adaptive biasing force (ABF) method, by projecting the estimated mean force onto a gradient. The associated stochastic process satisfies a non linear stochastic differential equation.

A Semi-Lagrangian scheme for a modified version of the Hughes model for pedestrian flow [PDF]

, 2016
In this paper we present a Semi-Lagrangian scheme for a regularized version of the Hughes model for pedestrian flow. Hughes originally proposed a coupled nonlinear PDE system describing the evolution of a large pedestrian group trying to exit a domain as

Vector Approximate Message Passing

IEEE Transactions on Information Theory, 2019
The standard linear regression (SLR) problem is to recover a vector $\mathrm {x}^{0}$ from noisy linear observations $\mathrm {y}=\mathrm {Ax}^{0}+\mathrm {w}$ . The approximate message passing (AMP) algorithm proposed by Donoho, Maleki, and Montanari

Multiobjective Simulated Annealing for Collision Avoidance in ATM Accounting for Three Admissible Maneuvers

Mathematical Problems in Engineering, Volume 2016, Issue 1, 2016., 2016
Technological advances are required to accommodate air traffic control systems for the future growth of air traffic. Particularly, detection and resolution of conflicts between aircrafts is a problem that has attracted much attention in the last decade becoming vital to improve the safety standards in free flight unstructured environments.

Emerging trends of scrub typhus disease in southern Rajasthan, India: A neglected public health problem

Journal of Vector Borne Diseases, 2022
Scrub typhus is the oldest known vector-borne zoonotic infectious disease in the world which is life-threatening for all age groups as it presents acute febrile illness along with multi-organ involvements and spread with the biting of infectious ...

Real-Time Action Recognition with Enhanced Motion Vector CNNs [PDF]

Computer Vision and Pattern Recognition, 2016
The deep two-stream architecture [23] exhibited excellent performance on video based action recognition. The most computationally expensive step in this approach comes from the calculation of optical flow which prevents it to be real-time.
