Gaussian process and bayesian optimization
WebMar 24, 2024 · For Gaussian processes in Bayesian optimization, a few acquisition functions are available in the literature, some of them have a known analytic form ( GP-UCB for example), are well studied and easy to implement. I am looking for an acquisition function similar to GP-UCB, for random forests surrogate model. WebSep 15, 2024 · Bayesian optimization works by constructing a posterior distribution of functions (gaussian process) that best describes the function you want to optimize. As the number of observations grows, the posterior distribution improves, and the algorithm becomes more certain of which regions in parameter space are worth exploring and …
