Research Abstract

In this project, the collaborative filtering preserving privacy was treated as a statistical inference in the information geometric framework. We studied the robust criterion for the privacy preservation and obtained the optimal condition. We further showed the relationship between beta divergence criterion of the information geometry and the H infinity filter in the field of robust control, which shows the possibility to apply the collaborative filtering to time series data. For the collaborative filtering, we developed the simultaneous optimization procedure of dimension reduction and clustering from Bayesian framework. Moreover, we found out a fairness-aware learning framework based on privacy preservation and investigated its fundamental property.
