关于多元高斯过程的注记

Remarks on multivariate Gaussian Process

Zexun Chen, Jun Fan, Kuo Wang

摘要:

高斯过程在现代统计学和概率论中占据主导地位,因为它们的重要性和大量强有力的结果。高斯过程的常见用途是与估计,检测和许多统计或机器学习模型相关的问题。随着高斯过程应用的快速发展,有必要巩固向量值随机过程,特别是多元高斯过程的基本理论,这是许多多个相关响应的应用问题的基本理论。本文在向量值函数空间上基于高斯测度给出了多元高斯过程的精确定义,并给出了其存在性证明。此外,还介绍了多元高斯过程的几个基本性质,如严格平稳性和独立性。我们进一步推导了多元布朗运动,包括作为多元高斯过程的一种特殊情况的伊藤引理,并简要介绍了多元高斯过程回归作为多输出预测问题的一种有用的统计学习方法。

英文摘要:

Gaussian processes occupy one of the leading places in modern statistics and probability theory due to their importance and a wealth of strong results. The common use of Gaussian processes is in connection with problems related to estimation, detection, and many statistical or machine learning models. With the fast development of Gaussian process applications, it is necessary to consolidate the fundamentals of vector-valued stochastic processes, in particular multivariate Gaussian processes, which is the essential theory for many applied problems with multiple correlated responses. In this paper, we propose a precise definition of multivariate Gaussian processes based on Gaussian measures on vector-valued function spaces, and provide an existence proof. In addition, several fundamental properties of multivariate Gaussian processes, such as strict stationarity and independence, are introduced. We further derive multivariate Brownian motion including Itô lemma as a special case of a multivariate Gaussian process, and present a brief introduction to multivariate Gaussian process regression as a useful statistical learning method for multi-output prediction problems.
