ChOracle: A Unified Statistical Framework for Churn Prediction

no code implementations15 Sep 2019 Ali Khodadadi, Seyed Abbas Hosseini, Ehsan Pajouheshgar, Farnam Mansouri, Hamid R. Rabiee

In this approach which is more realistic in real world online services, at each time-step the model predicts the user return time instead of predicting a churn label.

Predicting Anchor Links between Heterogeneous Social Networks

1 code implementation IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining 2016 Sina Sajadmanesh, Hamid R. Rabiee, Ali Khodadadi

Once a user (called source user) of a social network (called source network) joins a new social network (called target network), a new inter-network link (called anchor link) is formed between the source and target networks.
