An adaptative variance reduction method for Monte Carlo simulations that uses importance sampling scheme based on a change of drift and develops two applications of the procedure for variance reduction in a Monte Carlo computation in finance and in reliability.
Abstract
In this article we propose an adaptative variance reduction method for Monte Carlo simulations. The method uses importance sampling scheme based on a change of drift. The change of drift is selected adaptatively through the Monte Carlo computation by using a suitable sequence of approximation. We state and prove theoretical results supporting the use of the method. We develop two applications of the procedure for variance reduction in a Monte Carlo computation in finance and in reliability.

Computing VaR and CVaR using Stochastic Approximation and Adaptive Unconstrained Importance Sampling

TL;DR: A first Robbins–Monro (RM) procedure based on Rockafellar–Uryasev's identity for the CVaR and it is proved that the weak convergence rate of the resulting procedure is ruled by a Central Limit Theorem with minimal variance and its efficiency is illustrated on several typical energy portfolios.

Unconstrained Recursive Importance Sampling

TL;DR: In this paper, an unconstrained stochastic approximation method of finding the optimal measure change (in an a priori parametric family) for Monte Carlo simulations is proposed. But this method does not consider the regularity of the density of the law without assume smoothness of the payoff.
