    Asymptotics-guided learning and symbolic regression for dispersive resonances

    Konstantinos Alexopoulos, Josselin Garnier

    We study resonance prediction in dispersive media, formulated as nonlinear spectral problems for volume integral operators. The main idea is to use asymptotic analysis not only as a baseline approximation, but also as a guide for constructing predictive correction models. We learn the residual between asymptotic and reference resonances using features suggested by the subwavelength expansion, including the logarithmic scales specific to two...
