Gaussian or Normal Distribution is very common term in statistics. These are generally used to represent random variables which coming into Machine Learning we can say which is something like the error when we dont know the weight vector for our Linear Regression Model. pp 63-71 | They are attractive because of their flexible non-parametric nature and computational simplicity.

While usually modelling a large data it is common that more data is closer to the mean value and the very few or less frequent data is observed towards the extremes, which is nothing but a gaussian distribution that looks like this(μ = 0 and σ = 1): Adding to the above statement we can refer to Central limit theorem to stregthen the above assumption.

Gaussian Processes for Machine Learning Matthias Seeger Department of EECS University of California at Berkeley 485 Soda Hall, Berkeley CA 94720-1776, USA mseeger@cs.berkeley.edu February 24, 2004 Abstract Gaussian processes (GPs) are natural generalisations of multivariate Gaussian ran-dom variables to in nite (countably or continuous) index sets. Mean is usually represented by μ and variance with σ² (σ is the standard deviation). Gaussian Processes is a powerful framework for several machine learning tasks such as regression, classification and inference.

Given any set of N points in the desired domain of your functions, take a multivariate Gaussian whose covariance matrix parameter is the Gram matrix of your N points with some desired kernel, and sample from that Gaussian. But before we go on, we should see what random processes are, since Gaussian process is just a special case of a random process.

This work leverages recent advances in probabilistic machine learning to discover conservation laws expressed by parametric linear equations. The higher degrees of polynomials you choose, the better it will fit the observations. Of course, like almost everything in machine learning, we have to start from regression. : Regression and classification using Gaussian process priors (with discussion).

Part of Springer Nature. The central limit theorem (CLT) establishes that, in some situations, when independent random variables are added, their properly normalized sum tends toward a normal distribution (informally a “bell curve”) even if the original variables themselves are not normally distribute.
