拉丁超立方采样(Latin Hypercube Sampling, LHS)是一种统计采样技术,用于生成一组样本点,这些样本点在参数空间中均匀分布,并且满足每个维度只有一个样本点落在该维度的取值范围内。LHS常用于参数优化和模型验证等领域。在Python中,有几种常用的包可以进行拉丁超立方采样,下面介绍两种常用的方法。1. 使用pyDOE2包pyDOE2...
Latin Hypercube Sampling.. 拉丁超立方体抽样 --- (1979))在 “Technometrics” 提出了“拉丁超立方体抽样” (Latin Hypercube Sampling) (简称LHS) 的方法,并立即得到广泛的应用,一批学者对其理论和方法作了系统地研究和发展,形成了一个独立的分枝。
探索未知的科学殿堂,拉丁超立方采样(Latin Hypercube Sampling, LHS)与蒙特卡洛模拟如同夜空中的璀璨星辰,照亮了处理不确定性问题的迷雾。蒙特卡洛,这个名字本身就蕴含着一种随机的魔力,它通过海量的模拟实验,为我们揭示概率世界的奥秘,哪怕是看似简单的抛硬币游戏,也能借此估算出五次投掷中出现一次正...
拉丁超立方采样是一种特殊的采样方法,用于改进蒙特卡洛模拟中的随机抽样。它通过将样本空间分层,然后在每层内随机抽样,最后将样本打乱顺序,得到结果。相比于随机抽样,拉丁超立方采样在复杂分布场景下的效率更高,能够更均匀地覆盖样本空间,尤其是在正态分布等复杂分布的情况下。拉丁超立方采样的主要优点...

While researching the topic of Latin hypercube sampling (LHS), I read an article by Emily Gao (2019) that shows how to use PROC IML in SAS to perform the algorithm. It is possible to simplify Gao's implementation of Latin hypercube sampling in SAS while also making the computation more ...
algorithm (WOA) has shown promise in addressing this challenge, but issues persist, including poor stability, low efficiency, and accuracy in COVID-19 threshold image segmentation. To tackle these issues, we introduce a Latin hypercube sampling initialization-based multi-strategy enhanced WOA (CAGWOA...
