Abstract(in English) | Analysis and prediction of dynamic processes using data are fundamental in a variety of scientific and industrial fields, and have been discussed actively also in machine learning. Recently, operator-theoretic analysis of nonlinear dynamical systems, in particular analysis with Koopman operator, has attracted much attention due to the generality, the connection to physical concepts, and advances of estimation methods such as dynamic mode decomposition (DMD). In this talk, I first overview the basics of this research topics, focusing on spectral analysis of dynamical systems with Koopman operator. Then, I describe several recently-proposed related algorithms based on machine learning. In the talk, I occasionally show several applications of these method to several real-world data, with a focus on the ones we have worked on. |
