Scalable Prediction of Information Cascades over Arbitrary Time Horizons [article]

Daniel Haimovich, Dima Karamshuk, Thomas J. Leeper, Evgeniy Riabenko, Milan Vojnovic
2020 arXiv   pre-print
We propose a model for predicting an information cascade size at arbitrary time horizons based on Hawkes point processes with exponentially decaying intensity.  ...  The prediction task is difficult because view events are the result of complicated interactions between resharing, feed ranking algorithms, and organic features of the content popularity and network structure  ...  Content resharing events and post privacy settings govern the information spread in a network, with each reshare providing access to information to some uninformed users.  ...

Using network motifs to characterize temporal network evolution leading to diffusion inhibition [article]

Soumajyoti Sarkar, Ruocheng Guo, Paulo Shakarian
2019 arXiv   pre-print
We study the lifecycle of information cascades to understand what leads to saturation of growth in terms of cascade reshares, thereby resulting in expiration, an event we call "diffusion inhibition".  ...  We test features of motif patterns by using regression models for both individual patterns and their combination and we find that motifs as features are better predictors of the future network organization  ...  Acknowledgements Some of the authors are supported through the AFOSR Young Investigator Program (YIP) grant FA9550-15-1-0159, ARO grant W911NF-15-1-0282, and the DoD Minerva program grant N00014-16-1-2015  ...
