mlrMBOis a highly configurable R toolbox for model-based / Bayesian optimization of black-box functions. Features: EGO-type algorithms (Kriging with expected improvement) on purely numerical search spaces, seeJones et al. (1998) Mixed search spaces with numerical, integer, categorical and subordina...

There are several ways of applying the BA in optimization. The direct Bayesian approach (DBA) is defined by fixing aprior distribution Pon a set of functionsf(x) and by minimizing the Bayesian risk functionR(x) [6,14]. The risk function describes the average deviation from the global minimu...

“自举”(翻译自bootstrap)这个词汇在多个领域可能见到,它字面意思是提着靴子上的带子把自己提起来,这当然是不可能的,在机器学习领域可以理解为原样本自身的数据再抽样得出新的样本及统计量,也有被翻译为自助法的。 Bayesian Bootstrap是一个强大的方法,它比其他的自举法更快,并且可以给出更紧密的置信区间,并避免许...
