Bayesian Optimization Pure Python implementation of bayesian global optimization with gaussian processes. This is a constrained global optimization package built upon bayesian inference and gaussian processes, that attempts to find the maximum value of an unknown function in as few iterations as possible. ...
1. 解释什么是贝叶斯优化(Bayesian Optimization) 贝叶斯优化是一种全局优化方法,它利用贝叶斯推断来高效地找到目标函数的最大值或最小值。这种方法特别适用于目标函数评估成本高昂(如计算密集型或实验成本高)的场景。贝叶斯优化通过构建一个概率模型(通常是高斯过程)来近似目标函数,并使用这个模型来选择下一个评估点,以...
