哈密顿蒙特卡罗采样器已经成为MCMC实现的标准算法,而不是更基本的版本,但它们仍然需要一些调整和校准。利用NUTS算法的u型转弯准则(Hoffman and Gelman, 2014),我们提出了一个依赖于相关跨越式积分器的积分时间分布的HMC版本。此外,使用原始-对偶平均方法来调整积分器的步长,我们实现了一个基本的无校准版本的HMC。在多个基准测试中,与原始的NUTS相比,该算法的效率得到了显著提高。
Hamiltonian Monte Carlo samplers have become standard algorithms for MCMC implementations, as opposed to more basic versions, but they still require some amount of tuning and calibration. Exploiting the U-turn criterion of the NUTS algorithm (Hoffman and Gelman, 2014), we propose a version of HMC that relies on the distribution of the integration time of the associated leapfrog integrator. Using in addition the primal-dual averaging method for tuning the step size of the integrator, we achieve an essentially calibration free version of HMC. When compared with the original NUTS on several benchmarks, this algorithm exhibits a significantly improved efficiency.
