Sparse greedy gaussian process regression
Webproposed the Sparse Greedy Gaussian Process (SGGP), a method for learning the support set for given hyperparameters of the covariance function based on approximating the posterior. We show that approximating the posterior is un-satisfactory, since it fails to guarantee generalization, and propose a theoretically Web1. mar 2024 · Smola, A.J., Bartlett, P.: Sparse greedy Gaussian process regression.

WebFor Gaussian process regression, searching for an approximate solution to (4) relies on the assumption that a set of variables whose posterior probability is close to that of the mode … WebUse 50 points in the active set and sparse greedy matrix approximation ( 'sgma') method for active set selection. Because the scales of the first and second predictors are different, it is good practice to standardize the data.
Websue invloved in forward selection algorithms to sparse Gaussian Process Regression (GPR). Firstly, we re-examine a previous basis vector selection criterion proposed by Smola and … WebWe present a method for the sparse greedy approximation of Bayesian Gaussian process regression, featuring a novel heuristic for very fast forward selection. Our method is essentially as fast as an equivalent one which selects the "support" patterns at random, yet it can outperform random selection on hard curve fitting tasks.
