Filtering‐based approaches for functional data classification

Abstract

AbstractBecause of its many practical applications, classifying functional data has received considerable attention over the last decades. Most classification approaches for functional data are extended from those for multivariate data. During the extension, two strategies, namely filtering and regularization, have commonly been employed to tackle the issues raised by the fact that functional data are intrinsically infinite‐dimensional. Because of space limitations, we focus on the filtering methods in this review.This article is categorized under: Statistical and Graphical Methods of Data Analysis > Analysis of High Dimensional Data Statistical Learning and Exploratory Methods of the Data Sciences > Clustering and Classification
