Automatic recognition and tagging of topologically different regimes in dynamical systems
Jesse Berwald, Marian Gidea, Mikael Vejdemo-Johansson
Complex systems are commonly modeled using nonlinear dynamical systems. These models are often high-dimensional and chaotic. An important goal in studying physical systems through…
Critical Transitions In a Model of a Genetic Regulatory System
Jesse Berwald, Marian Gidea
We consider a model for substrate-depletion oscillations in genetic systems, based on a stochastic differential equation with a slowly evolving external signal. We show the existen…
Non-global parameter estimation using local ensemble Kalman filtering
Thomas Bellsky, Jesse Berwald, Lewis Mitchell
We study parameter estimation for non-global parameters in a low-dimensional chaotic model using the local ensemble transform Kalman filter (LETKF). By modifying existing technique…
