Opinion dynamics have attracted the interest of researchers from different fields. Local
interactions among individuals create interesting dynamics for the system as a whole. Such …

Recent years have witnessed a significant trend towards filling the gap between Social
Network Analysis (SNA) and control theory. This trend was enabled by the introduction of …

Unlike many complex networks studied in the literature, social networks rarely exhibit
unanimous behavior, or consensus. This requires a development of mathematical models …

In this paper, we consider discrete opinion dynamics with n possible opinions in social
networks with stubborn agents, where conformists adopt the most common opinions in their …

In this paper, we analyze data on the opinion dynamics of 1,660,927 users of an online
social network using formal models of opinion formation. We have observed that moderate …

The processes of information diffusion across social networks (for example, the spread of
opinions and the formation of beliefs) are attracting substantial interest in disciplines ranging …

This paper considers a new framework to detect communities in a graph from the
observation of signals at its nodes. We model the observed signals as noisy outputs of an …

The aim of this paper is to propose a novel methodology for estimating the social influence
among agents interacting in a sparse social network described by the Friedkin and Johnsen …

This paper models the cyber-social system as a cyber-network of agents monitoring states of
individuals in a social network. The state of each individual is represented by a social node …

The subject of this paper is the detection and mitigation of data injection attacks in
randomized average consensus gossip algorithms. It is broadly known that the main …
