A network provides powerful means of representing complex relationships between entities by abstracting entities as vertices, and relationships as edges connecting vertices in a …
We propose a dynamic network model where two mechanisms control the probability of a link between two nodes:(i) the existence or absence of this link in the past, and (ii) node …
Our focus is on realistically modeling and forecasting dynamic networks of face-to-face contacts among individuals. Important aspects of such data that lead to problems with …
Change-point detection in dynamic networks is a challenging task which is particularly due to the complex nature of temporal graphs. Existing approaches are based on the extraction …

The issue of modelling observations generated in matrix form over time is key in economics, finance and many domains of application. While it is common to model vectors of …
Modeling time series of multilayer network data is challenging due to the peculiar characteristics of real-world networks, such as sparsity and abrupt structural changes …
Modeling sequential data is essential to many applications such as natural language processing, recommendation systems, time series predictions, anomaly detection, etc. When …

Real-world graphs like social networks are often evolutionary over time, whose observations at different timestamps lead to graph sequences. Modeling such evolutionary graphs is …
Latent space models are popular for analyzing dynamic network data. We propose a variational approach to estimate the model parameters and the latent positions of the nodes …
