摘要:

高斯过程(GP)的状态空间(SS)表示是近年来研究的热点.主要原因是它允许在O(n)内计算基于GP的推断,其中$n$是观察的数量。这种实现使GPS适合大数据。因此,提供机器学习中使用的最重要内核的SS表示是很重要的。本文的目的是展示如何利用SS模型的瞬态行为映射到SS模型的非平稳内核。

英文摘要:

The state space (SS) representation of Gaussian processes (GP) has recently gained a lot of interest. The main reason is that it allows to compute GPs based inferences in O(n), where $n$ is the number of observations. This implementation makes GPs suitable for Big Data. For this reason, it is important to provide a SS representation of the most important kernels used in machine learning. The aim of this paper is to show how to exploit the transient behaviour of SS models to map non-stationary kernels to SS models.
