Balancing the trade-off between cost and reliability for wireless sensor networks: a multi-objective optimized deployment method

1 code implementation19 Jul 2022 Long Chen, Yingying Xu, Fangyi Xu, Qian Hu, Zhenzhou Tang

In addition, this work fully considers the heterogeneity of SNs (i. e. differentiated sensing range and deployment cost) and three-dimensional (3-D) deployment scenarios.

PA-ResSeg: A Phase Attention Residual Network for Liver Tumor Segmentation from Multi-phase CT Images

no code implementations27 Feb 2021 Yingying Xu, Ming Cai, Lanfen Lin, Yue Zhang, Hongjie Hu, Zhiyi Peng, Qiaowei Zhang, Qingqing Chen, Xiongwei Mao, Yutaro Iwamoto, Xian-Hua Han, Yen-Wei Chen, Ruofeng Tong

In this paper, we propose a phase attention residual network (PA-ResSeg) to model multi-phase features for accurate liver tumor segmentation, in which a phase attention (PA) is newly proposed to additionally exploit the images of arterial (ART) phase to facilitate the segmentation of portal venous (PV) phase.

Learning performance in inverse Ising problems with sparse teacher couplings

no code implementations25 Dec 2019 Alia Abbara, Yoshiyuki Kabashima, Tomoyuki Obuchi, Yingying Xu

These results are considered to be exact in the thermodynamic limit on locally tree-like networks, such as the regular random or Erd\H{o}s--R\'enyi graphs.

High-dimensional structure learning of binary pairwise Markov networks: A comparative numerical study

no code implementations14 Jan 2019 Johan Pensar, Yingying Xu, Santeri Puranen, Maiju Pesonen, Yoshiyuki Kabashima, Jukka Corander

Learning the undirected graph structure of a Markov network from data is a problem that has received a lot of attention during the last few decades.

Approximate message passing for nonconvex sparse regularization with stability and asymptotic analysis

no code implementations8 Nov 2017 Ayaka Sakata, Yingying Xu

Through asymptotic analysis, we show the correspondence between the density evolution of SCAD-AMP and the replica symmetric solution.
