Learning Lévy density via adaptive RKHS regression with bi-level optimization
Numerical experiments demonstrate that the bilevel RKHS method provides a more stable and competitive alternative to classical L-curve and generalized cross-validation strategies and that the adaptive RKHS norm is more accurate and robust than Lρ2- and ℓ2-norms for regularization.
