Abstract: A method is developed for integrating experimental data and mathematical models so that a comprehensive description of a physical system can be constructed for engineering analysis. The computational requirements of the method can be modest depending on the computational complexity of the associated mathematical models. Using a feedforward artificial neural network architecture, numerical examples involving the extrapolation of a physical system response at unmeasured coordinates and processing of noisy experimental measurements demonstrate the utility of the method.
