Throughput Optimization in UAV-Mounted RIS using DRL

Published:Dec 31, 2025 10:36
1 min read
ArXiv

Analysis

This paper addresses a practical problem in wireless communication: optimizing throughput in a UAV-mounted Reconfigurable Intelligent Surface (RIS) system, considering real-world impairments like UAV jitter and imperfect channel state information (CSI). The use of Deep Reinforcement Learning (DRL) is a key innovation, offering a model-free approach to solve a complex, stochastic, and non-convex optimization problem. The paper's significance lies in its potential to improve the performance of UAV-RIS systems in challenging environments, while also demonstrating the efficiency of DRL-based solutions compared to traditional optimization methods.
Reference

“The proposed DRL controllers achieve online inference times of 0.6 ms per decision versus roughly 370-550 ms for AO-WMMSE solvers.”

Proximal Subgradient Algorithm for Constrained Multiobjective DC-type Optimization

Published:Dec 31, 2025 08:31
1 min read
ArXiv

Analysis

This paper addresses a challenging class of multiobjective optimization problems involving non-smooth and non-convex objective functions. The authors propose a proximal subgradient algorithm and prove its convergence to stationary solutions under mild assumptions. This is significant because it provides a practical method for solving a complex class of optimization problems that arise in various applications.
Reference

“Under mild assumptions, the sequence generated by the proposed algorithm is bounded and each of its cluster points is a stationary solution.”

Derivative-Free Optimization for Quantum Chemistry

Published:Dec 30, 2025 23:15
1 min read
ArXiv

Analysis

This paper investigates the application of derivative-free optimization algorithms to minimize Hartree-Fock-Roothaan energy functionals, a crucial problem in quantum chemistry. The study's significance lies in its exploration of methods that don't require analytic derivatives, which are often unavailable for complex orbital types. The use of noninteger Slater-type orbitals and the focus on challenging atomic configurations (He, Be) highlight the practical relevance of the research. The benchmarking against the Powell singular function adds rigor to the evaluation.
Reference

“The study focuses on atomic calculations employing noninteger Slater-type orbitals. Analytic derivatives of the energy functional are not readily available for these orbitals.”

Robust Reduced Rank Regression for Heavy-Tailed Noise and Missing Data

Published:Dec 30, 2025 20:09
1 min read
ArXiv

Analysis

This paper addresses the limitations of classical Reduced Rank Regression (RRR) methods, which are sensitive to heavy-tailed errors, outliers, and missing data. It proposes a robust RRR framework using Huber loss and non-convex spectral regularization (MCP and SCAD) to improve accuracy in challenging data scenarios. The method's ability to handle missing data without imputation and its superior performance compared to existing methods make it a valuable contribution.
Reference

“The proposed methods substantially outperform nuclear-norm-based and non-robust alternatives under heavy-tailed noise and contamination.”

Linear Program Witness for Network Nonlocality

Published:Dec 26, 2025 10:15
1 min read
ArXiv

Analysis

This paper addresses the challenging problem of certifying network nonlocality in quantum information processing. The non-convex nature of network-local correlations makes this a difficult task. The authors introduce a novel linear programming witness, offering a potentially more efficient method compared to existing approaches that suffer from combinatorial constraint growth or rely on network-specific properties. This work is significant because it provides a new tool for verifying nonlocality in complex quantum networks.
Reference

“The authors introduce a linear programming witness for network nonlocality built from five classes of linear constraints.”

Historical Information Accelerates Decentralized Optimization: A Proximal Bundle Method

Published:Dec 17, 2025 08:40
1 min read
ArXiv

Analysis

The article likely discusses a novel optimization method for decentralized systems, leveraging historical data to improve efficiency. The focus is on a 'proximal bundle method,' suggesting a technique that combines proximal operators with bundle methods, potentially for solving non-smooth or non-convex optimization problems in a distributed setting. The use of historical information implies the method is designed to learn from past iterations, potentially leading to faster convergence or better solutions compared to methods that do not utilize such information. The source being ArXiv indicates this is a research paper, likely detailing the theoretical underpinnings, algorithmic details, and experimental validation of the proposed method.
