A Simple Algorithm for Scalable Monte Carlo Inference

Alexander Borisenko, Maksym Byshkin, Alessandro Lomi

摘要:

统计物理学的方法被广泛用于复杂网络的建模。基于最近提出的均衡期望方法,我们导出了指数族分布参数的极大似然估计(MLE)的一个简单有效的算法.指数族分布是一类统计模型,包括Ising模型、Markov随机场和指数随机图模型.计算实验和经验数据的分析表明,该算法增加了数量级的网络数据的大小服从蒙特卡罗为基础的推理。我们报告的结果表明,该算法的适用性可以很容易地扩展到分析大样本的依赖性的观察,通常发现在生物学,社会学,天体物理学和生态学。

英文摘要:

The methods of statistical physics are widely used for modelling complex networks. Building on the recently proposed Equilibrium Expectation approach, we derive a simple and efficient algorithm for maximum likelihood estimation (MLE) of parameters of exponential family distributions - a family of statistical models, that includes Ising model, Markov Random Field and Exponential Random Graph models. Computational experiments and analysis of empirical data demonstrate that the algorithm increases by orders of magnitude the size of network data amenable to Monte Carlo based inference. We report results suggesting that the applicability of the algorithm may readily be extended to the analysis of large samples of dependent observations commonly found in biology, sociology, astrophysics, and ecology.
