摘要翻译:
提出了一种构造马尔可夫链转移核的新的几何方法。我们的方法总是使平均拒绝率最小化,甚至在许多相关情况下将其降至零,这是传统方法无法实现的,如Metropolis-Hastings算法或Herat bath算法(Gibbs sampler)。此外,几何方法不仅可以求出无排斥跃迁概率的可逆解,而且可以求出无排斥跃迁概率的不可逆解。这是第一个在一般情况下可以构造不可逆转移核的通用方法。我们证明了Potts模型的自相关时间(渐近方差)是传统Metropolis-Hastings算法的6倍以上。我们的算法适用于几乎所有的Markov链Monte Carlo方法,提高了算法的效率。

英文摘要:
  We introduce a new geometric approach that constructs a transition kernel of Markov chain. Our method always minimizes the average rejection rate and even reduce it to zero in many relevant cases, which cannot be achieved by conventional methods, such as the Metropolis-Hastings algorithm or the heat bath algorithm (Gibbs sampler). Moreover, the geometric approach makes it possible to find not only a reversible but also an irreversible solution of rejection-free transition probabilities. This is the first versatile method that can construct an irreversible transition kernel in general cases. We demonstrate that the autocorrelation time (asymptotic variance) of the Potts model becomes more than 6 times as short as that by the conventional Metropolis-Hastings algorithm. Our algorithms are applicable to almost all kinds of Markov chain Monte Carlo methods and will improve the efficiency.
