| Abstract | Data assimilation combines observation and data from a mathematical model to compute the best initial condition. Inverse problems can be classified according to the nature of the estimated property type: source term, system property, boundary condition, and initial condition. Extended Kalman filter (EKF) and four dimensional variational method (4D-Var) are two procedures employed to perform DA. Artificial neural networks are applied here for reducing the computational complexity for a given DA scheme. The supervised multi-layer perceptron is used to emulate the Kalman filter. The designed neural network was implemented on a FPGA (Field-programmable Gate Array), employed as a co-processor. The linear 1D wave equation is the dynamical system used for testing the framework. A good performance was obtained with neural network emulating the Kalman filter, with an average error 5.18E- 05 (software and FPGA comparison) on the FPGA implementation. |
