Epidemic spreading on time-varying multiplex networks
Quan-Hui Liu, Xinyue Xiong, Qian Zhang +1
Social interactions are stratified in multiple contexts and are subject to complex temporal dynamics. The systematic study of these two features of social systems has started only…
Unsupervised Domain Adaptive Re-Identification: Theory and Practice
Liangchen Song, Cheng Wang, Lefei Zhang +4
We study the problem of unsupervised domain adaptive re-identification (re-ID) which is an active topic in computer vision but lacks a theoretical foundation. We first extend exist…
Impacts of Opinion Leaders on Social Contagions
Quan-Hui Liu, Feng-Mao Lü, Qian Zhang +2
Opinion leaders are ubiquitous in both online and offline social networks, but the impacts of opinion leaders on social behavior contagions are still not fully understood, especial…
Resonance-based Secure Pairing for Wearables
Wei Wang, Lin Yang, Qian Zhang
Securely pairing wearables with another device is the key to many promising applications. This paper presents \textit{Touch-And-Guard (TAG)}, a system that uses hand touch as an in…
Configurations and Diagnosis for Ultra-Dense Heterogeneous Networks: From Empirical Measurements to Technical Solutions
