Simultaneous Tensor Completion and Denoising by Noise Inequality Constrained Convex Optimization

open access: yesIEEE Access, 2019
Convex optimization, rather than a non-convex approach, still play important roles in many computer science applications because of its exactness and efficiency.

Research on Multibeam Pattern Synthesis of Time Modulated Array Based on Convex Optimization

open access: yesInternational Journal of Antennas and Propagation, 2021
An efficient multibeam pattern synthesis method for time modulated array (TMA) is proposed in this paper. The aim of this method is to generate a beam pattern on the specified sideband of TMA. The pattern synthesis problem is divided into two stages.

Doubly Constrained Waveform Optimization for Integrated Sensing and Communications

open access: yesSensors, 2023
This paper investigates threshold-constrained joint waveform optimization for an integrated sensing and communication (ISAC) system. Unlike existing studies, we employ mutual information (MI) and sum rate (SR) as sensing and communication metrics ...

Learning Convex Optimization Models [PDF]

open access: yesarXiv, 2020
A convex optimization model predicts an output from an input by solving a convex optimization problem. The class of convex optimization models is large, and includes as special cases many well-known models like linear and logistic regression. We propose a heuristic for learning the parameters in a convex optimization model given a dataset of input ...

Quasi-convex optimization

open access: yesJournal of Mathematical Analysis and Applications, 1986
Given a bounded real function f defined on a closed bounded real interval I, the problem is to find a quasi-convex function f′ so as to minimize the supremum of |f(s)-f′(s)| for all s in I, over the class of all quasi-convex functions f′ on I. This article obtains optimal solutions to the problem and derives their properties. This problem arises in the

Fuzzy convexity and multiobjective convex optimization problems

open access: yesComputers & Mathematics with Applications, 2006
AbstractIn this paper, based on the more restrictive definition of fuzzy convexity due to Ammar and Metz [1], several useful composition rules are developed. The advantages in using the more restrictive definition of fuzzy convexity are that local optimality implies global optimality, and that any convex combination of such convex fuzzy sets is also a ...

Efficient Convex Optimization of Reentry Trajectory via the Chebyshev Pseudospectral Method

open access: yesInternational Journal of Aerospace Engineering, 2019
A novel sequential convex (SCvx) optimization scheme via the Chebyshev pseudospectral method is proposed for efficiently solving the hypersonic reentry trajectory optimization problem which is highly constrained by heat flux, dynamic pressure, normal ...

Optimal Resource Allocation for Two-User and Single-DF-Relay Network With Ambient Backscatter

open access: yesIEEE Access, 2019
In this paper, we investigate and analyze a two-user single decode-and-forward (DF) relay network with ambient backscatter communication capabilities, where the user nodes and the relay node are equipped with a wireless-powered device instead of embedded

Sharp boundary regularity for some degenerate-singular Monge-Ampère Equations on k-convex domain [PDF]

open access: yesarXiv, 2023
We introduce the concept of k-strictly convexity to describe the accurate convexity of convex domains some directions of which boundary may be flat. Basing this accurate convexity, we construct sub-solutions the Dirichlet problem for some degenerate-singular Monge-Amp\`ere type equations and prove the sharp boundary estimates for convex viscosity ...
