NeuralPDE: Modelling Dynamical Systems from Data

چکیده
Many physical processes such as weather phenomena or fluid mechanics are governed by partial differential equations (PDEs). Modelling dynamical systems using Neural Networks is an active research field. However, current methods still very limited, they do not exploit the knowledge about nature of system, require extensive prior governing limited to linear first-order equations. In this work we make observation that Method Lines used solve PDEs can be represented convolutions which makes convolutional neural networks (CNNs) natural choice parametrize arbitrary PDE dynamics. We combine parametrization with differentiable ODE solvers form NeuralPDE Model, explicitly takes into account fact data show in several experiments on toy and real-world our model consistently outperforms state-of-the-art models learn systems.

A szerző célja, hogy komplex módszereket mutasson be a dinamikai rendszerek modellezésére. Jelen írás az elektromos, mechanikai és elektro-mechanikus rendszerekre, vagyis a mechatronikai rendszerekre fókuszál. A matematikai modellezés a legfontosabb fázis az automatikus rendszerek elemzésében és azok előzetes tervezésében. Szerző a számítógépes elemzés és tervezés területeire koncentrál, amely ...
متن کاملDynamical modelling of superstatistical complex systems
We show how to construct the optimum superstatistical dynamical model for a given experimentally measured time series. For this purpose we generalise the superstatistics concept and study a Langevin equation with a memory kernel whose parameters fluctuate on a large time scale.We showhow to construct a synthetic dynamicalmodelwith the same invariant density and correlation function as the exper...
متن کاملCHASSIS - Inverse Modelling of Relaxed Dynamical Systems
The state of a non-relativistic gravitational dynamical system is known at any time t if the dynamical rule, i.e. Newton’s equations of motion, can be solved; this requires specification of the gravitational potential. The evolution of a bunch of phase space coordinates w is deterministic, though generally non-linear. We discuss the novel Bayesian non-parametric algorithm CHASSIS that gives pha...
