Smac bayesian optimization
Webb28 okt. 2024 · Both Auto-WEKA and Auto-sklearn are based on Bayesian optimization (Brochu et al. 2010). Bayesian optimization aims to find the optimal architecture quickly without reaching a premature sub-optimal architecture, by trading off exploration of new (hence high-uncertainty) regions of the search space with exploitation of known good …
