Bayesian multiple-network multi-layer exponential random graph models (MNML-ERGMs): developing efficient inference and application to neuroimaging
… network. The exponential random graph model (ERGM) belongs to such models, which characterise the distribution of networks through a set of network summary statistics. Each summary statistic provides a topological summary of a network, and ERGM is empowered by its flexibility to incorporate a …

Lifted probabilistic relational inference for uncertain networks
… algorithm for Exponential Random Graph Model (ERGM) -- a family of statistical models, which are closely related to PRGM. An ERGM defines a probabilistic distribution of all graphs of $n$ nodes using a set of subgraph statistics. The main insight enabling this advance is that subgraph …

Expressivity and Structure in Networks: Ising Models, Random Graphs, and Neural Networks.
… Ising Model b) Exponential Random Graph Model (ERGM) c) Random Geometric Graphs (RGG) d) Neural Networks, where for each a version of this question is posed and solved. For the case of Ising Model, ERGM, and RGG, we establish statistical tests which can distinguish them from the respective …

Recent Advances on Statistical Network Analysis and Multi-task Learning for Complex Data
… propose a novel exponential random graph model (ERGM) to study the common knowledge (CK) phenomenon in Facebook social networks. Unlike traditional contagion models, CK allows individuals to coordinate their activation as a group, thereby facilitating both the initiation and propagation of …

Structure and evolution of communication networks in organizations
… (MRQAP) and Exponential Random Graph Models (ERGM), we identify significant factors affecting the size and shape of communication networks. These parameters include organizational structure, homophily, job position, and physical proximity. We record the evolution of the networks and discuss …

A Network Approach to Nuclear Deterrence
… centrality. Exponential Random Graph Models (ERGM) test the propensity to form ties of nuclear influence based on three dimensions of DIME (DIE) and controlling for structural factors. Initial results suggest that DIE do not play a significant role in affecting a state’s nuclear ties in the …

Collaboration in scientific digital ecosystems: A socio-technical network analysis
… 7-years using exponential random graph models (ERGM). This paper applies theory of network (network science) to model network formation patterns in developer community. The third paper, like the first, applies network theory and to understand user network characteristics and communication …

Choosing team members: taking personality and perceived personality into account
Technological advances have led to an increase in teams that self-assemble, meaning individuals have more power to choose whom they want to work with. This study aims to understand the mechanisms behind teammate choice. Specifically, a qualitative study and a social network approach were used to …

A Dyadic Approach to Leadership Emergence
Leadership emergence is best conceptualized as a complex, multi-level process arising from the dynamic interplay of all elements in the process: group members, relations, and context (Day, 2014). This study seeks to simultaneously examine to the role of each in the leadership emergence process by …

ELITES AND SOCIAL MEDIA. EXPLORATORY STUDY ON ELITES' BEHAVIOUR ON SOCIAL MEDIA AND TECHNOCRATIC, TECHNO-POPULIST AND POPULIST ATTITUDES
… By means of exponential random graph model (Ergm), we find significant levels of homophily within each elite. On the other hand, we test several hypotheses on the likelihood of being a central actor within the general and restricted networks. The third chapter explores elites’ attitudes in …
