WebIn this paper, we propose a Robust Batch Bayesian Optimization approach (RBBO) for analog circuit synthesis. Local penalization (LP) is used to capture the local repulsion between query points in one batch. The diversity of the query points can thus be guaranteed. The failed points and their neighborhoods can also be excluded by LP. WebDec 2, 2024 · Risk-averse Heteroscedastic Bayesian Optimization.

WebDec 3, 2024 · Bayesian optimization (BO) is an indispensable tool to optimize objective functions that either do not have known functional forms or are expensive to evaluate. Currently, optimal experimental... WebBayesian optimization is a powerful approach for the global derivative-free opti- mization of non-convex expensive functions. Even though there is a rich literature on Bayesian optimization, the source code of advanced methods is rarely available, making it difficult for practitioners to use them and for researchers to compare to and extend them.

WebRoBo can optimize any function with X as an numpy array and Y as an numpy array. Thereby is the number of points you want to evaluate at and is the dimension of the input X.
