Outline of Final Research Achievements

Due to the wide spread of data mining technologies, the problem of unfair decisions with respect to social sensitive information, such as gender or race, have been arising. To alleviate the problem, the techniques of fairness-aware data mining have been studied.
In this project, we develop methods of data transformation while maintaining fairness, and these methods are applied to recommendation tasks. Our main contributions are as follows: (1) We developed fairness-aware probabilistic matrix factorization model with a regularization terms, adopting Gaussian mutual information and Bhattacharyya distance. (2) We developed a topic model for collaborative filtering while maintaining independence from sensitive information.
