其实BO不是只能用来调超参的,因为他是一个非常general的gradient-free global optimization的方法,所以他的适用场景一般有两个特点:(1)需要优化的function计算起来非常费时费力,比如上面提到的神经网络的超参问题,每一次训练神经网络都是燃烧好多GPU的;(2)你要优化的function没有导数信息。所以如果你遇到的问题有以上...

Bayesian optimization has emerged as an efficient approach to optimizing expensive functions, but it has not been, to the best of our knowledge, applied to constrained multi-objective optimization of structural concrete design problems. In this work, we develop a Bayesian optimization framework ...
We present MixMOBO, the first mixed variable, multi-objective Bayesian optimization framework for such problems. Using MixMOBO, optimal Pareto-fronts for multi-objective, mixed variable design spaces can be found efficiently while ensuring diverse solutions. The method is sufficiently flexible to ...
