Researchers have introduced gp2Scale, a novel methodology designed to scale Gaussian processes to handle over 10 million data points without resorting to approximations like inducing points or kernel interpolation. This approach leverages the inherent sparse structure within the covariance matrix, enabled by flexibly designed, compactly supported, and non-stationary kernels. The method demonstrates superior performance in many cases compared to state-of-the-art approximation algorithms, while also maintaining agnosticism towards arbitrary kernel designs, noise models, and mean functions, making it suitable for a wide range of modern Gaussian process applications.
