Fast Data-Driven greedy Sensor Selection for Ridge Regression
收藏 引用
IEEE SENSORS JOURNAL 2025年 第6期25卷 10030-10045页
作者: Sasaki, Yasuo Yamada, Keigo Nagata, Takayuki Saito, Yuji Nonomura, Taku Nagoya Univ Dept Aerosp Engn Nagoya 4648603 Japan Tohoku Univ Dept Aerosp Engn Sendai 9808579 Japan Tohoku Univ Frontier Res Inst Interdisciplinary Sci Sendai 9808578 Japan
We propose a data-driven sensor-selection algorithm for accurate estimation of the target variables from the selected measurements. The target variables are assumed to be estimated by a ridge-regression estimator, whi... 详细信息

Approximation ratio of the min-degree greedy algorithm for Maximum Independent Set on interval and chordal graphs
收藏 引用
DISCRETE APPLIED MATHEMATICS 2025年 360卷 275-281页
作者: Chaplick, Steven Frohn, Martin Kelk, Steven Lottermoser, Johann Mihalak, Matus Maastricht Univ Dept Adv Comp Sci DACS Maastricht Netherlands
In this article we prove that the minimum-degree greedy algorithm, with adversarial tie-breaking, is a (2/3)-approximation for the MAXIMUM INDEPENDENT SET problem on interval graphs. We show that this is tight, even o... 详细信息

greedy Selection for Heterogeneous Sensors
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 2025年 73卷 1394-1409页
作者: Majumder, Kaushani Pillai, Sibi Raj B. Mulleti, Satish Indian Inst Technol Dept Elect Engn Mumbai 400076 India
Simultaneous operation of all sensors in a large-scale sensor network is power-consuming and computationally expensive. Hence, it is desirable to select fewer sensors. A greedy algorithm is widely used for sensor sele... 详细信息

m-BRe: New Variants for the Backward Replacement Approach to Enhance the Compression Capabilities of the Forward greedy Pursuit
收藏 引用
IEEE ACCESS 2024年 12卷 138646-138662页
作者: Omara, A. N. Alotaibi, Abdullah Shawan Elect Res Inst Comp & Syst Dept Cairo 4473221 Egypt Shaqra Univ Comp Sci Dept Shaqra 11911 Saudi Arabia Ahram Canadian Univ Fac Comp Sci & Informat Technol Giza 3221405 Egypt
This paper introduces two variants of the backward replacement approach, T-BRe and H-BRe, aimed at enhancing the compression capabilities of forward greedy pursuit algorithms. The effectiveness of these methods is eva... 详细信息

Adaptive meshfree approximation for linear elliptic partial differential equations with PDE-greedy kernel methods
收藏 引用
BIT NUMERICAL MATHEMATICS 2025年 第1期65卷 1-36页
作者: Wenzel, Tizian Winkle, Daniel Santin, Gabriele Haasdonk, Bernard Ludwig Maximilians Univ Munchen Dept Math Munich Germany Univ Stuttgart Inst Stochast & Applicat Stuttgart Germany Ca Foscari Univ Venice Venice Italy Univ Stuttgart Inst Appl Anal & Numer Simulat Stuttgart Germany
We consider meshless approximation for solutions of boundary value problems (BVPs) of elliptic Partial Differential Equations (PDEs) via symmetric kernel collocation. We discuss the importance of the choice of the col... 详细信息

A succinct and approximate greedy algorithm for the Minimum Set Cover Problem
收藏 引用
JOURNAL OF COMPUTATIONAL SCIENCE 2024年 81卷
作者: Delgado, Jorge Ferrada, Hector Navarro, Cristobal A. Univ Austral Chile Inst Informat Valdivia Chile
The Minimum Set Cover Problem (MSCP) is a combinatorial optimization problem belonging to the NP- Hard class in computer science. For this reason, there is no algorithm that in the worst case ensures finding an optima... 详细信息

greedy sets and greedy numerical semigroups
收藏 引用
COMMUNICATIONS IN ALGEBRA 2025年 第6期53卷 2442-2455页
作者: Perez-Roses, Hebert Serradilla-Merinero, Jose Miguel Bras-Amoros, Maria Univ Rovira & Virgili Dept Comp Sci & Math Avda Paisos Catalans 26 Catalonia 43007 Spain
Motivated by the change-making problem, we extend the notion of greediness to sets of positive integers not containing the element 1, and from there to numerical semigroups. We provide an algorithm to determine if a g... 详细信息

ALGORITHMICA 2024年 第11期86卷 3518-3578页
作者: Krysta, Piotr Mari, Mathieu Zhi, Nan Augusta Univ Augusta GA USA Univ Montpellier LIRMM CNRS Montpellier France Univ Liverpool Liverpool England
We study the approximability of the maximum size independent set (MIS) problem in bounded degree graphs. This is one of the most classic and widely studied NP-hard optimization problems. It is known for its inherent h... 详细信息
