Catch'Em All: Locating Multiple Diffusion Sources in Networks with Partial Observations
Kai Zhu, Zhen Chen, Lei Ying
This paper studies the problem of locating multiple diffusion sources in networks with partial observations. We propose a new source localization algorithm, named Optimal-Jordan-Co…
Source Localization in Networks: Trees and Beyond
Kai Zhu, Lei Ying
Information diffusion in networks can be used to model many real-world phenomena, including rumor spreading on online social networks, epidemics in human beings, and malware on the…
Locating Contagion Sources in Networks with Partial Timestamps
Kai Zhu, Zhen Chen, Lei Ying
This paper studies the problem of identifying the contagion source when partial timestamps of a contagion process are available. We formulate the source localization problem as a r…
A Robust Information Source Estimator with Sparse Observations
Kai Zhu, Lei Ying
In this paper, we consider the problem of locating the information source with sparse observations. We assume that a piece of information spreads in a network following a heterogen…
Information Source Detection in the SIR Model: A Sample Path Based Approach
Kai Zhu, Lei Ying
This paper studies the problem of detecting the information source in a network in which the spread of information follows the popular Susceptible-Infected-Recovered (SIR) model. W…
