A machine learning inversion scheme for determining effective interaction of charged colloidal suspensions using scattering

ORAL

Abstract

We outline a machine learning strategy for determining the effective interaction of charged colloidal suspensions using scattering. We showed that the effective potential can be probabilistically inferred from the scattering spectra without any restriction imposed by model assumptions. Comparisons to existing parametric approaches demonstrate the superior performance of this method in accuracy, efficiency, and applicability. This method can effectively enable quantification of interaction in highly correlated systems using scattering and diffraction experiments.
