Abstract: An initialization method is developed for feedforward artificial neural networks trained to model physical systems. The construction requires imposing certain constraints on the values of the input, bias, and output weights. The attribution of certain roles to each of these parameters allows for mapping a polynomial approximation into an artificial neural network architecture. Attention is focused on time-independent partial differential equations modelled by the feedforward artificial neural network architecture, in conjunction with the popular hyperbolic tangent transfer function. Moreover, this approach is shown to be capable of incorporating other smooth neuron transfer functions. A numerical example is presented illustrating the accuracy and utility of the method.
