函数型数据的特征选择

Feature Selection for Functional Data

Ricardo Fraiman, Yanina Gimenez, Marcela Svarc

AI总结:

本文针对函数型数据提出了一种基于用户定义函数集的特征选择方法,该方法在一般假设下具有一致性,并在分类、回归和主成分分析中表现出良好效果。

摘要:

本文研究了当数据为函数型数据时的特征选择问题,我们考察了包括分类、回归和主成分分析在内的多种统计方法。盲化方法的一个优点是它非常灵活,因为特征由用户根据所研究问题提出的一组相关函数定义。我们的方法在一组相当一般的假设下是一致的,并且在我们分析的真实数据示例中产生了良好的结果。

英文摘要:

In this paper we address the problem of feature selection when the data is functional, we study several statistical procedures including classification, regression and principal components. One advantage of the blinding procedure is that it is very flexible since the features are defined by a set of functions, relevant to the problem being studied, proposed by the user. Our method is consistent under a set of quite general assumptions, and produces good results with the real data examples that we analyze.
