Some advanced topics in statistics are taught. In particular, topics and theories related to machine learning are taught. More specifically, high dimensional data analysis methods and its theory are explained, and, in addition, a nonparametric method called "kernel method", unsupervised learning methods, and learning theory are taught. Moreover, efficient optimization techniques for machine learning are explained.
[Objectives] Statistical science and machine learning are disciplines in which useful information is extracted from data to aid human decision making. Students will learn methodology not simply as knowledge, but also learning the background theory including the validity of those methods to promote understanding the essence. Students will broadly apply all kinds of techniques to a variety of problems, learning to construct new techniques on one's own.
[Topics] Students in this course will learn several of statistical science's more advanced techniques, based on their connection to various application fields. We will focus in particular on the connection with machine learning, introducing central topics from both statistical science and machine learning.
