Abstract

Density ratio estimation is a comprehensive statistical data processing framework, and it includes various statistical data processing tasks such as transfer learning, outlier detection, cross-domain matching, and change-point detection, to name a few. In this talk, I will first present direct density-ratio estimation methods and their applications to transfer learning, outlier detection, change-point detection, and cross-domain object matching. Then, I will introduce our recent results of density-ratio estimation in deep learning and high-dimensional modeling.
