Robust Graph Learning Under Wasserstein Uncertainty

no code implementations10 May 2021 Xiang Zhang, Yinfei Xu, Qinghe Liu, Zhicheng Liu, Jian Lu, Qiao Wang

To this end, we propose a graph learning framework using Wasserstein distributionally robust optimization (WDRO) which handles uncertainty in data by defining an uncertainty set on distributions of the observed data.

Liquefaction-induced Plasticity from Entropy-boosted Amorphous Ceramics

no code implementations1 Feb 2021 Haidong Bian, Quanfeng He, Junhua Luan, Yu Bu, Yong Yang, Zhengtao Xu, Jian Lu, Yang Yang Li

Ceramics are easy to break, and very few generic mechanisms are available for improving their mechanical properties, e. g., the 1975-discovered anti-fracture mechanism is strictly limited to zirconia and hafnia.

Analysis of Adaptive Synchrosqueezing Transform with a Time-varying Parameter

no code implementations22 Aug 2020 Jian Lu, Qingtang Jiang, Lin Li

A model-guided deep network for limited-angle computed tomography

1 code implementation10 Aug 2020 Wei Wang, Xiang-Gen Xia, Chuanjiang He, Zemin Ren, Jian Lu, Tianfu Wang, Baiying Lei

In this paper, we first propose a variational model for the limited-angle computed tomography (CT) image reconstruction and then convert the model into an end-to-end deep network. We use the penalty method to solve the model and divide it into three iterative subproblems, where the first subproblem completes the sinograms by utilizing the prior information of sinograms in the frequency domain and the second refines the CT images by using the prior information of CT images in the spatial domain, and the last merges the outputs of the first two subproblems.
