WebApr 3, 2024 · GPyOpt is a Python open-source library for Bayesian Optimization developed by the Machine Learning group of the University of Sheffield. It is based on GPy, a Python framework for Gaussian process modelling. In this article, we demonstrate how to use this package to do hyperparameter search for a classification problem with Scikit-learn. 2. WebWe introduce two novel ε-greedy acquisition functions. Extensive empirical evaluation of these together with random search, purely exploratory, and purely exploitative search on 10 benchmark problems in 1 to 10 dimensions shows that ε-greedy algorithms are generally at least as effective as conventional acquisition functions (e.g., EI and UCB ... how do i lighten a pdf
