Query: Bayesian Inference of Spreading Processes on Networks   Infectious diseases are studied to understand their spreading mechanisms, to
evaluate control strategies and to predict the risk and course of future
outbreaks. Because people only interact with a small number of individuals, and
because the structure of these interactions matters for spreading processes,
the pairwise relationships between individuals in a population can be usefully
represented by a network. Although the underlying processes of transmission are
different, the network approach can be used to study the spread of pathogens in
a contact network or the spread of rumors in an online social network. We study
simulated simple and complex epidemics on synthetic networks and on two
empirical networks, a social / contact network in an Indian village and an
online social network in the U.S. Our goal is to learn simultaneously about the
spreading process parameters and the source node (first infected node) of the
epidemic, given a fixed and known network structure, and observations about
state of nodes at several points in time. Our inference scheme is based on
approximate Bayesian computation (ABC), an inference technique for complex
models with likelihood functions that are either expensive to evaluate or
analytically intractable. ABC enables us to adopt a Bayesian approach to the
problem despite the posterior distribution being very complex. Our method is
agnostic about the topology of the network and the nature of the spreading
process. It generally performs well and, somewhat counter-intuitively, the
inference problem appears to be easier on more heterogeneous network
topologies, which enhances its future applicability to real-world settings
where few networks have homogeneous topologies.
