Dynamic Orthogonal Matching Pursuit for Sparse Data Reconstruction

open access: yesIEEE Open Journal of Signal Processing, 2023
The orthogonal matching pursuit (OMP) is one of the mainstream algorithms for sparse data reconstruction or approximation. It acts as a driving force for the development of several other greedy methods for sparse data reconstruction, and it also plays a ...

Multi-Objective Models for Sparse Optimization in Linear Support Vector Machine Classification

open access: yesMathematics, 2023
The design of linear Support Vector Machine (SVM) classification techniques is generally a Multi-objective Optimization Problem (MOP). These classification techniques require finding appropriate trade-offs between two objectives, such as the amount of ...

Sparse noncommutative polynomial optimization

open access: yesMathematical Programming, 2021
This article focuses on optimization of polynomials in noncommuting variables, while taking into account sparsity in the input data. A converging hierarchy of semidefinite relaxations for eigenvalue and trace optimization is provided. This hierarchy is a noncommutative analogue of results due to Lasserre [SIAM J. Optim. 17(3) (2006), pp.

Optimal Sparse Regression Trees

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2023
Regression trees are one of the oldest forms of AI models, and their predictions can be made without a calculator, which makes them broadly useful, particularly for high-stakes applications. Within the large literature on regression trees, there has been little effort towards full provable optimization, mainly due to the computational hardness of the ...

Seismic diffraction detection method for geological hidden disasters in coal mining

open access: yes矿业科学学报, 2022
The geological hidden disaster-causing bodies such as small-scale faults and collapsed columns may destroy the continuity of the coal seam, which will lead to accidents such as gas outburst and water outburst in the air mining area, and seriously ...
