About this blog

Hello, this is Kyoichi living in Tokyo*1, and I'll study Data analysis for my work. I graduated master course in mathematics, and the speciality was diffential topological geometry then.

In this blog, I'd like to post mathematical contexts, which will be used in actual data analysis. Actually, they will be mainly my notes.

Please leave your comments, if you have any opinions for my posts.


Thank you:)
