“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...
Owing to the high cost associated with carrying out experiments, scientists in both areas set numerous (hyper)parameter values by evaluating only a small subset of the possible configurations. Bayesian optimization, an iterative response surface-based global optimization algorithm, has demonstrated ...
Among these, scikit-learn and Pypl are the most commonly used packages. It should be noted that scikit-learn and Pypl are not specially developed for the kNN algorithm; they contain many other machine learning algorithms. In addition, Bergstra et al. [29] developed Hyperopt to define a ...
