Privacy-preserving ranking over vertically partitioned data

Keivan Kianmehr, Negar Koochakzadeh
2012 Proceedings of the 2012 Joint EDBT/ICDT Workshops on - EDBT-ICDT '12  
Privacy concerns in many application domains prevents sharing of data, which limits data mining technology to identify patterns and trends from large amount of data.  ...  By vertically partitioned data, each site contains some attributes of the entities in the environment.  ...  To simulate vertically partitioned data, we randomly distribute 102 predictor features in two different sites.  ...

Multiplex Network Regression: How do relations drive interactions? [article]

Giona Casiraghi
2020 arXiv   pre-print
We introduce a statistical regression model to investigate the impact of dyadic relations on complex networks generated from observed repeated interactions.  ...  To demonstrate the power of our approach, we investigate an example based on empirical data.  ...  We can build the fourth predictor using the social networks obtained from self-reported friendship relations. Because this data is self-reported, it generates a directed social network.  ...
