Hamiltonian monte carlo algorithm
WebHessian from first-order information. In particular, we present a Hamiltonian Monte Carlo algorithm in which the variance of the momentum variables is based on a BFGS approximation. The key point is that we use a limited memory approximation, in which only a small window of previous samples are used to the approximate the Hessian.
