Title: Optimal filtering of nonlinear stochastic systems: Exact tractable solutions and stability properties
Abstract: In this talk I will discuss a novel statistical approach in developing the exact and tractable solutions of optimal filtering in nonlinear stochastic systems. Stability properties of the optimal nonlinear filter are derived. Higher order implicit Runge-Kutta method is proposed for numerical solutions of the nonlinear filtering equations. Numerical examples are discussed to verify the accuracy of theoretical findings.
Speaker #2: Stephen Marsland
Title: Why are birdcalls like elastic bands?
Abstract: When I first started to think about how to classify the species of birds from the calls I used my favourite tool — geodesics on diffeomorphism groups. I will explain why this wasn't as insane as it sounds, and consider a few other interesting mathematical questions in bioacoustic analysis.
