为了更好地恢复历史海表温度,建立一个良好的校正模型是非常重要的。本文基于异方差高斯过程(GP)回归方法,提出了一种新的烯酮(${\rm{U}}_{37}^{\rm{K}'}$)模型。我们的非参数方法不仅处理的变量模式的噪声在SST,但也包含一个贝叶斯方法分类潜在的离群值。
To restore the historical sea surface temperatures (SSTs) better, it is important to construct a good calibration model for the associated proxies. In this paper, we introduce a new model for alkenone (${\rm{U}}_{37}^{\rm{K}'}$) based on the heteroscedastic Gaussian process (GP) regression method. Our nonparametric approach not only deals with the variable pattern of noises over SSTs but also contains a Bayesian method of classifying potential outliers.
