MCMC、蒙特卡洛近似和Metropolis算法简介 编程算法机器学习神经网络深度学习人工智能 MCMC 是Markov Chain Monte Carlo 的简称,但在传统模拟中有一个很重要的假设是样本是独立的(independent samples),这一点在贝叶斯统计尤其是高纬度的模型中很难做到。所以MCMC的目的就是运用蒙特卡洛模拟出一个马可链(
Markov chain Monte Carlo (MCMC) estimation provides a solution to the complex integration problems that are faced in the Bayesian analysis of statistical problems. The implementation of MCMC algorithms is, however, code intensive and time consuming. We have developed a Python package, which is ...

Markov Chain Monte Carlo简称MCMC,是一个抽样方法,用于解决难以直接抽样的分布的随机抽样模拟问题。 在基础概率课我们有学过,已知一个概率分布函数F(X),那么用电脑产生服从Uniform分布的随机数U,代入F−1(X),那么X=F−1(U)就是服从F(X)的随机变量。这个方法在金融领域使用很广,即Monte Carlo Simulation:通...
