Modeling Memory Imprints Induced by Interactions in Social Networks
James Flamino, Ross DeVito, Omar Lizardo +1
Memory imprints of the significance of relationships are constantly evolving. They are boosted by social interactions among people involved in relationships, and decay between such…
A Machine Learning Approach to Predicting Continuous Tie Strengths
James Flamino, Ross DeVito, Boleslaw K. Szymanski +1
Relationships between people constantly evolve, altering interpersonal behavior and defining social groups. Relationships between nodes in social networks can be represented by a t…
The power of dynamic social networks to predict individuals' mental health
Shikang Liu, David Hachen, Omar Lizardo +3
Precision medicine has received attention both in and outside the clinic. We focus on the latter, by exploiting the relationship between individuals' social interactions and their…
Heterogeneous network approach to predict individuals' mental health
Shikang Liu, Fatemeh Vahedian, David Hachen +4
Depression and anxiety are critical public health issues affecting millions of people around the world. To identify individuals who are vulnerable to depression and anxiety, predic…
Social Networks through the Prism of Cognition
Radosław Michalski, Bolesław K. Szymański, Przemysław Kazienko +3
Human relations are driven by social events-people interact, exchange information, share knowledge and emotions, and gather news from mass media. These events leave traces in human…
Influence of Personal Preferences on Link Dynamics in Social Networks
Ashwin Bahulkar, Boleslaw K. Szymanski, Nitesh Chawla +2
We study a unique network dataset including periodic surveys and electronic logs of dyadic contacts via smartphones. The participants were a sample of freshmen entering university…
Analysis of Link Formation, Persistence and Dissolution in NetSense Data
Ashwin Bahulkar, Boleslaw K. Szymanski, Omar Lizardo +3
We study a unique behavioral network data set (based on periodic surveys and on electronic logs of dyadic contact via smartphones) collected at the University of Notre Dame.The par…
Do the Young Live in a "Smaller World" Than the Old? Age-Specific Degrees of Separation in Human Communication
Yuxiao Dong, Omar Lizardo, Nitesh V. Chawla
In this paper, we investigate the phenomenon of "age-specific small worlds" using data from a large-scale mobile communication network approximating interaction patterns at societa…
Weighted reciprocity in human communication networks
Cheng Wang, Anthony Strathman, Omar Lizardo +3
In this paper we define a metric for reciprocity---the degree of balance in a social relationship---appropriate for weighted social networks in order to investigate the distributio…
Predictors of short-term decay of cell phone contacts in a large scale communication network
Troy Raeder, Omar Lizardo, David Hachen +1
Under what conditions is an edge present in a social network at time t likely to decay or persist by some future time t + Delta(t)? Previous research addressing this issue suggests…
