47th IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
作者: Kuroda, Hiroki Kitahara, Daichi Ritsumeikan Univ Coll Informat Sci & Engn Kyoto Japan
In this paper, we present a novel convex method for the graph-structured sparse recovery. While various structured sparsities can be represented as the graph-structured sparsity, graph-structured sparse recovery remai... 详细信息

OPTIMIZATION METHODS & SOFTWARE 2024年 第3期39卷 664-698页
作者: Van Dessel, Guillaume Glineur, Francois UCLouvain ICTEAM INMA Louvain La Neuve Belgium UCLouvain CORE Louvain La Neuve Belgium UCLouvain ICTEAM INMA 4 Ave Georges Lemaitre Louvain La Neuve Belgium
Several recent works address the impact of inexact oracles in the convergence analysis of modern first-order optimization techniques, e.g. Bregman Proximal Gradient and Prox-Linear methods as well as their accelerated... 详细信息

INFORMATION AND INFERENCE-A JOURNAL OF THE IMA 2024年 第4期13卷
作者: Montanari, Andrea Wu, Yuchen Stanford Univ Dept Stat Stanford CA 94305 USA Stanford Univ Dept Math Stanford CA 94305 USA Univ Penn Wharton Sch Dept Stat & Data Sci Philadelphia PA 19104 USA
We consider a class of statistical estimation problems in which we are given a random data matrix ${\boldsymbol{X}}\in{\mathbb{R}}{n\times d}$ (and possibly some labels ${\boldsymbol{y}}\in{\mathbb{R}}{n}$) and would ... 详细信息
