Gaussian Process Regression一、高斯分布高斯过程(Gaussian Process, GP)是随机过程之一,是一系列符合正态分布的随机变量在一指数集(index set)内的集合。该解释中的“指数”可以理解为“维度“,按照机器学习的角度,各个指数上的随机变量可以对应地理解为各个维度上的特征。

高斯过程回归(Gaussian Process Regression) 技术标签:机器学习数据分析 在概率论和统计学中,高斯过程是指观测发生在连续域(例如:时域、空间域)中的一种特殊的概率模型 1 基本概念 在高斯过程,连续的输入空间的任何点与正态分布的随机变量相关,而且任何随机变量的有限集合满足多重正态分布,例如变量间的任意线性组合是...
We present LonGP, an additive Gaussian process regression model that is specifically designed for statistical analysis of longitudinal data, which solves these commonly faced challenges. LonGP can model time-varying random effects and non-stationary signals, incorporate multiple kernel learning, and ...
In this paper, we present EV ent-triggered A ugmented R efitting of Gaussian Process Regression for S easonal Data (EVARS-GPR), a novel online algorithm that is able to handle sudden shifts in the target variable scale of seasonal data. For this purpose, EVARS-GPR combines online change...
What is the desired addition or change? Wanted a Gaussian Process Regressor in C++. I have some experience in writing GPs from scratch in python, so if possible, I would love to contribute. What is the motivation for this feature? Probab...
Gaussian Process (GP) regression models typically assume that residuals are Gaussian and have the same variance for all observations. However, applications with input-dependent noise (heteroscedastic residuals) frequently arise in practice, as do applications in which the residuals do not have a ...
