Here we present a non-parameteric appraoch to dealing with systematic effects in cosmological data analysis. We present a method that allows one to marginalize over a space of functions, such that unknown functional behaviour can be accounted for. We present an application of this technique to dark energy studies for future gravitational lensing experiments.

Keywords: Non-parameteric; Cosmology; Marginalization
