新的LazyHMC方法实现了无限维概率程序的哈密顿蒙特卡洛

研究人员开发了LazyHMC,这是一种新的哈密顿蒙特卡洛(HMC)公式,专为使用惰性求值并在无限维参数空间中运行的概率程序而设计。该方法解决了传统HMC的局限性,传统HMC需要梯度和有限维空间。LazyHMC利用Haskell中的惰性求值来处理随机过程和非参数贝叶斯模型,从而在无限维中实现基于梯度的HMC。该方法包括一种新颖的自动微分分析,证明了即使对于无限维、惰性定义的程序,似然函数的梯度也具有有限的支持。实验证明了其在混合高斯聚类、随机游走和分段常数回归等应用中的有效性。 AI

影响 为概率编程引入了一种新颖的计算方法,有可能增强复杂、无限维场景中贝叶斯建模和推理的能力。
