拓扑密度估计

Topological density estimation

Steve Huntsman

摘要:

我们介绍\emph{topological density estimation}(TDE),其中的概率密度函数的多模态结构的拓扑推断,随后用于执行内核密度估计的带宽选择。我们表明,TDE的性能和运行时间的优势,竞争的内核密度估计高度多模态概率密度函数的方法。我们还表明,TDE产生有用的辅助信息,它可以确定自己的适合使用,我们解释了它的性能。

英文摘要:

We introduce \emph{topological density estimation} (TDE), in which the multimodal structure of a probability density function is topologically inferred and subsequently used to perform bandwidth selection for kernel density estimation. We show that TDE has performance and runtime advantages over competing methods of kernel density estimation for highly multimodal probability density functions. We also show that TDE yields useful auxiliary information, that it can determine its own suitability for use, and we explain its performance.
