Instead of adopting an \\emph{ad hoc} analytic ansatz, we use a multilayer perceptron to learn \\(\\Phi'(z)\\) as a smooth function of the holographic coordinate, with \\(\\Phi(0)=0\\) imposed to ensure ultraviolet consistency. The dilaton and its derivatives obtained by automatic differentiation generate the holographic potential \\(U(z)\\), and the associated Schr\\\"odinger-like equation is discretized and diagonalized to extract the low-lying eigenmodes.
