I will consider the problem of probabilistic model checking of temporal logic formulae on stochastic processes with parametric uncertainty. This is computationally challenging, as in principle one needs an expensive model checking step for each value of the model parameters. We show that the dependence of truth probabilities on parameters is differentiable, which allows us to construct an efficient statistical learning approach to solve the problem: we collect a sparse sample of parameter/ truth probability pairs, and treat them as a training set for a machine learning predictor based on Gaussian Processes. Due to the smoothness result, this approach converges to the true value in the large sample size. I will further discuss how these ideas can be generalised in a system design/ identification context.
