It has long been a significant but difficult problem to identify propagation sources based on
limited knowledge of network structures and the varying states of network nodes. In practice …

Social networks have greatly amplified spread of information across different communities.
However, we recently observe that various malicious information, such as computer virus …

A belief propagation approach has been recently proposed for the patient-zero problem in
SIR epidemics. The patient-zero problem consists of finding the initial source of an epidemic …

Investigating into the past history of an epidemic outbreak is a paramount problem in
epidemiology. Based on observations about the state of individuals, on the knowledge of the …

The topological structure of many real networks changes with time. Thus, locating the
sources of a temporal network is a creative and challenging problem, as the enormous size …

In order to solve the problem of source node detection when privacy information leakage
occurs in social networks, especially in the case of asynchronous propagation and low …

Locating the source of information in online social networks facilitates knowing the origins of
events, verifying the authenticity of information and finding the initial spreaders of rumors …

Witnessing the wide spread of malicious information in large networks, we develop an
efficient method to detect anomalous diffusion sources and thus protect networks from …

We investigate the information-theoretical limits of inference tasks in epidemic spreading on
graphs in the thermodynamic limit. The typical inference tasks consist in computing …

In recent years, research on methods for locating a source of spreading phenomena in
complex networks has seen numerous advances. Such methods can be applied not only to …
