First-Order Sampling Schemes with Langevin Dynamics: There exists a bulk of literature on (stochastic) rst-order sampling schemes derived from Langevin Dynamics or its variants [1, 4{6, 8, 9, 12, 14, 16, 20, 26, 32]. However, to our knowledge, this work is the rst to consider mirror descent extensions of the Langevin Dynamics.

Langevin dynamics for black-box sampling. We explore two surrogate approaches. The ﬁrst approach exploits zero-order approximation of gradients in the Langevin Sampling and we refer to it as Zero-Order Langevin. In practice, this approach can be prohibitive since we still need to often query the expensive PDE solvers. The
