Nonlinear Hawkes Processes in Time-Varying System
Feng Zhou, Quyu Kong, Yixuan Zhang +2
Hawkes processes are a class of point processes that have the ability to model the self- and mutual-exciting phenomena. Although the classic Hawkes processes cover a wide range of…
Contact Tracing: Computational Bounds, Limitations and Implications
Quyu Kong, Manuel Garcia-Herranz, Ivan Dotu +1
Contact tracing has been extensively studied from different perspectives in recent years. However, there is no clear indication of why this intervention has proven effective in som…
Birdspotter: A Tool for Analyzing and Labeling Twitter Users
Rohit Ram, Quyu Kong, Marian-Andrei Rizoiu
The impact of online social media on societal events and institutions is profound; and with the rapid increases in user uptake, we are just starting to understand its ramifications…
Evently: Modeling and Analyzing Reshare Cascades with Hawkes Processes
Quyu Kong, Rohit Ram, Marian-Andrei Rizoiu
Modeling online discourse dynamics is a core activity in understanding the spread of information, both offline and online, and emergent online behavior. There is currently a discon…
Describing and Predicting Online Items with Reshare Cascades via Dual Mixture Self-exciting Processes
Quyu Kong, Marian-Andrei Rizoiu, Lexing Xie
It is well-known that online behavior is long-tailed, with most cascaded actions being short and a few being very long. A prominent drawback in generative models for online events…
Modeling Information Cascades with Self-exciting Processes via Generalized Epidemic Models
Quyu Kong, Marian-Andrei Rizoiu, Lexing Xie
Epidemic models and self-exciting processes are two types of models used to describe diffusion phenomena online and offline. These models were originally developed in different sci…
