The method for inverse problems applies even if the underlying ordinary differential equation is partially or completely not explicitly known which is the case with many technical applications. This procedure is interpreted in terms of Polynomial Neural Networks (PNNs). The physical knowledge is incorporated into the network since its architecture is designed on directly top of the Taylor Map approach. This does not only improve the data efficiency but also reduce the effort of the included training procedure. On this basis we demonstrate the application on a system of catalytic reaction equations to highlight the capabilities of this method in practice. Thus, the PNN approach can also be used as a meta or surrogate model.
