Abstract
A datatset on is a finite topological space. Current research of a dataset focuses on statistical methods and the algebraic topological method \cite{carlsson}. In \cite{hu}, the concept of typed topological space was introduced and showed to have the potential for studying finite topological spaces, such as a dataset. It is a new method from the general topology perspective. A typed topological space is a topological space whose open sets are assigned types. Topological concepts and methods can be redefined using open sets of certain types. In this article, we develop a special set of types and its related typed topology on a dataset . Using it, we can investigate the inner structure of . In particular, has a natural quotient space, in which is organized into tracks, and each track is split into components. Those components are in a order. Further, they can be…
