Prediction of Dynamical Systems with Composition Networks 1 Prediction of Dynamical Systems with Composition Networks

In this paper we study the problem of predicting dynamical systems from discrete-time measurements of the state variables. Our approach is based on the theory of Lie algebras and the Baker-Campbell-Hausdorr formula. We present the composition network which is a multi-layer architecture which can use the a priori knowledge we have about the system. We also introduce the "MLP in dynamics space" which is a general implementation of the composition network having a universal approximation property. We demonstrate the eeciency of the proposed method on the task of predicting the Lorenz attractor.
