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.",
