Analysis of Degrees of Freedom in Scattered Fields for Nonlinear Inverse Scattering Problems
Zhichao Lin, Rui Guo, Tao Shan +4
In the study of nonlinear inverse scattering problems (ISPs), the traditional method for estimating the number of degrees of freedom (NDoF) of the scattered field does not consider…
Mediation analysis with the mediator and outcome missing not at random
Shuozhi Zuo, Debashis Ghosh, Peng Ding +1
Mediation analysis is widely used for investigating direct and indirect causal pathways through which an effect arises. However, many mediation analysis studies are challenged by m…
A Probabilistic Imaginary Time Evolution Algorithm Based on Non-unitary Quantum Circuit
Hao-Nan Xie, Shi-Jie Wei, Fan Yang +4
Imaginary time evolution is a powerful tool applied in quantum physics, while existing classical algorithms for simulating imaginary time evolution suffer high computational comple…
Learning Interpretable Decision Rule Sets: A Submodular Optimization Approach
Fan Yang, Kai He, Linxiao Yang +4
Rule sets are highly interpretable logical models in which the predicates for decision are expressed in disjunctive normal form (DNF, OR-of-ANDs), or, equivalently, the overall mod…
Geo-Localization via Ground-to-Satellite Cross-View Image Retrieval
Zelong Zeng, Zheng Wang, Fan Yang +1
The large variation of viewpoint and irrelevant content around the target always hinder accurate image retrieval and its subsequent tasks. In this paper, we investigate an extremel…
UniVIP: A Unified Framework for Self-Supervised Visual Pre-training
Zhaowen Li, Yousong Zhu, Fan Yang +9
Self-supervised learning (SSL) holds promise in leveraging large amounts of unlabeled data. However, the success of popular SSL methods has limited on single-centric-object images…
Learning Optical Flow with Adaptive Graph Reasoning
Ao Luo, Fan Yang, Kunming Luo +3
Estimating per-pixel motion between video frames, known as optical flow, is a long-standing problem in video understanding and analysis. Most contemporary optical flow techniques l…
