Time plays an essential role in the diffusion of information, influence and disease over networks. In many cases we only observe when a node copies information, makes a decision or becomes infected – but the connectivity, transmission rates between nodes and transmission sources are unknown. Inferring the underlying dynamics is of outstanding interest since it enables forecasting, influencing a...

In real world social networks, there are multiple diffusion processes which are rarely independent. They usually interact with each other in a competitive or cooperative manner. In this paper, motivated by the reinforcement theory in sociology, we model the adoption behavior of users in social networks by a multivariate marked Hawkes process. According to this model, the intensity of a user to ...

This work studies the problem of inferring whether an agent is directly influenced by another agent over an adaptive diffusion network. Agent i influences agent j if they are connected (according to the network topology), and if agent j uses the data from agent i to update its online statistic. The solution of this inference task is challenging for two main reasons. First, only the output of th...

Cascading processes, such as disease contagion, viral marketing, and information diffusion, are a pervasive phenomenon in many types of networks. The problem of devising intervention strategies to facilitate or inhibit such processes has recently received considerable attention. However, a major challenge is that the underlying network is often unknown. In this paper, we revisit the problem of ...

Information, disease, and influence diffuse over networks of entities in both natural systems and human society. Analyzing these transmission networks plays an important role in understanding the diffusion processes and predicting future events. However, the underlying transmission networks are often hidden and incomplete, and we observe only the time stamps when cascades of events happen. In t...

The topic in question is concerned with the sociological aspect of literature referring to Iran’s literary and historical experience. The basis of sociological criticism is built on the premise that literary works are the products of social life and that a comprehensive understanding of a work without considering its social aspects is impractical. To reach a better, more scientific, and more pr...
