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.

Recurrent Poisson Factorization for Temporal Recommendation

1 code implementation4 Mar 2017 Seyed Abbas Hosseini, Keivan Alizadeh, Ali Khodadadi, Ali Arabzadeh, Mehrdad Farajtabar, Hongyuan Zha, Hamid R. Rabiee

Poisson factorization is a probabilistic model of users and items for recommendation systems, where the so-called implicit consumer data is modeled by a factorized Poisson distribution.

Continuous-Time User Modeling in the Presence of Badges: A Probabilistic Approach

no code implementations7 Feb 2017 Ali Khodadadi, Seyed Abbas Hosseini, Erfan Tavakoli, Hamid R. Rabiee

However, typical point process based models often considered the impact of peer influence and content on the user participation and neglected other factors.

HNP3: A Hierarchical Nonparametric Point Process for Modeling Content Diffusion over Social Media

no code implementations2 Oct 2016 Seyed Abbas Hosseini, Ali Khodadadi, Soheil Arabzade, Hamid R. Rabiee

These capabilities allow the proposed model to adapt its temporal and topical complexity according to the complexity of data, which makes it a suitable candidate for real world scenarios.
