Modeling Customer Complain Behavior: A Neural Matrix Factorization Approach

We propose a deep learning approach which incorporates prior domain knowledge into a principled probabilistic matrix factorization framework to enhance complain behavior predictions as well as their interpretability.

Virtual Humans in Health-Related Interventions: A Meta-Analysis

We systematically evaluated evidence from controlled studies of interventions using virtual humans on their effectiveness in health-related outcomes. The design and implementation characteristics of these systems were also examined.
