Gaussian problem with the distance matrix
WebMay 11, 2024 · The set of stochastic process states f (x) of the wind speed input variables obeys an n-dimensional joint Gaussian distribution, and the probability function is denoted by GP. From the viewpoint of function space, full statistical characteristics of GP can be fully determined by the mean function m (x) and the covariance function matrix K (x, x
