*讲座内容简介：

Bayesian filtering and transfer operators have significant connection and play important roles in stochastic dynamical systems. There exist two transfer operators: Koopman operator and Perron-Frobenius operator.  In the talk, I will discuss two problems:  (1) Bayesian filtering is used to correct the approximation of Koopman operator in noisy dynamical systems; (2) Perron-Frobenius operator filter is derived in Bayesian filtering.  The application is investigated in data-driven modeling.
