Unsupervised Image Classification by Ideological Affiliation from User-Content Interaction Patterns
Xinyi Liu, Jinning Li, Dachun Sun +6
The proliferation of political memes in modern information campaigns calls for efficient solutions for image classification by ideological affiliation. While significant advances h…
Cost Function Learning in Memorized Social Networks with Cognitive Behavioral Asymmetry
Yanbing Mao, Jining Li, Naira Hovakimyan +2
This paper investigates the cost function learning in social information networks, wherein the influence of humans' memory on information consumption is explicitly taken into accou…
Unsupervised Belief Representation Learning with Information-Theoretic Variational Graph Auto-Encoders
Jinning Li, Huajie Shao, Dachun Sun +6
This paper develops a novel unsupervised algorithm for belief representation learning in polarized networks that (i) uncovers the latent dimensions of the underlying belief space a…
DyDiff-VAE: A Dynamic Variational Framework for Information Diffusion Prediction
Ruijie Wang, Zijie Huang, Shengzhong Liu +7
This paper describes a novel diffusion model, DyDiff-VAE, for information diffusion prediction on social media. Given the initial content and a sequence of forwarding users, DyDiff…
Dynamics of Public Opinion Evolution with Asymmetric Cognitive Bias
Yanbing Mao, Naira Hovakimyan, Tarek Abdelzaher
In this paper, we propose a pubic opinion model with incorporation of asymmetric cognitive bias: confirmation bias and negativity bias. We then investigate the generic modeling gui…
Social System Inference from Noisy Observations
Yanbing Mao, Naira Hovakimyan, Tarek Abdelzaher +1
This paper studies social system inference from a single trajectory of public evolving opinions, wherein observation noise leads to the statistical dependence of samples on time an…
paper2repo: GitHub Repository Recommendation for Academic Papers
Huajie Shao, Dachun Sun, Jiahao Wu +7
GitHub has become a popular social application platform, where a large number of users post their open source projects. In particular, an increasing number of researchers release r…
The Paradox of Information Access: On Modeling Social-Media-Induced Polarization
Chao Xu, Jinyang Li, Tarek Abdelzaher +3
The paper develops a stochastic model of drift in human beliefs that shows that today's sheer volume of accessible information, combined with consumers' confirmation bias and natur…
Hierarchical Overlapping Belief Estimation by Structured Matrix Factorization
Chaoqi Yang, Jinyang Li, Ruijie Wang +6
Much work on social media opinion polarization focuses on a flat categorization of stances (or orthogonal beliefs) of different communities from media traces. We extend in this wor…
The Age of Social Sensing
Dong Wang, Boleslaw K. Szymanski, Tarek Abdelzaher +2
Online social media, such as Twitter and Instagram, democratized information broadcast, allowing anyone to share information about themselves and their surroundings at an unprecede…
Resiliency and Robustness of Complex, Multi-Genre Networks
Alexander Kott, Tarek Abdelzaher
We explore the resiliency and robustness of systems while viewing them as complex, multi-genre networks. The term "complex, multi-genre networks" refers to networks that combine se…
