Abstract

A previous study analyzed the convergence of probability densities for forward and inverse problems when a sequence of approximate maps between model inputs and outputs converges in L^∞. This work generalizes the analysis to cases where the approximate maps converge in Lp for any 1≤ p < ∞. Specifically, under the assumption that the approximate maps converge in Lp, the convergence of probability density functions solving either forward or inverse problems is proven in Lq where the value of 1≤ q
