Created by DataCamp.com. This semester my studies all involve one key mathematical object: Gaussian processes.I’m taking a course on stochastic processes (which will talk about Wiener processes, a type of Gaussian process and arguably the most common) and mathematical finance, which involves stochastic differential equations (SDEs) used for derivative pricing, including in the Black-Scholes-Merton equation. This Gist is a brief demo Gaussian process models in some sense bring together work in the two communities. We illustrate the use of the The mean is a function of \(x\) (which is often the zero function), ... R package. These methods are provided as R functions in the package. The package utilizes a number of R packages. Our aim is to understand the Gaussian process (GP) as a prior over random functions, a posterior over functions given observed data, as a tool for spatial data modeling and surrogate modeling for computer experiments, and simply as a flexible nonparametric regression. Let's start from a regression problem example with a set of observations. Dear All, I am struggling to find an R package which contains a function for building a Gaussian Process model for binary classification which may produce prediction intervals for predicted probabilities. Longitudinal Gaussian process regression (R package) - jtimonen/lgpr. Thank you very much in advance.
