Hastings算法

Understanding the Hastings Algorithm

David D. L. Minh, Do Le, Minh

摘要:

Hastings算法是计算科学中的一个重要工具。虽然在数学上可以通过详细的平衡来证明,但在概念上很难理解。在这里,我们提出了两种互补和直观的方法来推导和理解算法。在我们的框架中,可以直接看到著名的梅特罗波利斯-黑斯廷斯算法在所有黑斯廷斯算法中具有最高的接受概率。

英文摘要:

The Hastings algorithm is a key tool in computational science. While mathematically justified by detailed balance, it can be conceptually difficult to grasp. Here, we present two complementary and intuitive ways to derive and understand the algorithm. In our framework, it is straightforward to see that the celebrated Metropolis-Hastings algorithm has the highest acceptance probability of all Hastings algorithms.
