Interest surrounding cryptocurrencies, digital or virtual currencies that are used as a medium for financial transactions, has grown tremendously in recent years. The anonymity sur…
Latent Space Model for Multi-Modal Social Data
Yoon-Sik Cho, Greg Ver Steeg, Emilio Ferrara +1
With the emergence of social networking services, researchers enjoy the increasing availability of large-scale heterogenous datasets capturing online user interactions and behavior…
Scalable Link Prediction in Dynamic Networks via Non-Negative Matrix Factorization
Linhong Zhu, Dong Guo, Junming Yin +2
We propose a scalable temporal latent space model for link prediction in dynamic social networks, where the goal is to predict links over time based on a sequence of previous graph…
Statistical Tests for Contagion in Observational Social Network Studies
Greg Ver Steeg, Aram Galstyan
Current tests for contagion in social network studies are vulnerable to the confounding effects of latent homophily (i.e., ties form preferentially between individuals with similar…
Information-Theoretic Measures of Influence Based on Content Dynamics
Greg Ver Steeg, Aram Galstyan
The fundamental building block of social influence is for one person to elicit a response in another. Researchers measuring a "response" in social media typically depend either on…
Co-evolution of Selection and Influence in Social Networks
Yoon-Sik Cho, Greg Ver Steeg, Aram Galstyan
Many networks are complex dynamical systems, where both attributes of nodes and topology of the network (link structure) can change with time. We propose a model of co-evolving net…
