Structural components in functional data. [PDF]

open access: yes, 2009
Analyzing functional data often leads to finding common factors, for which functional principal component analysis proves to be a useful tool to summarize and characterize the random variation in a function space.

Point Processes in a Metric Space and Their Applications

open access: yesMathematics, 2022
Point processes are important in extreme value theory due to their equivalent formulations of two popular models in various applications: the block maxima models and the peak-over-threshold model.

Non-Parametric Conditional U-Processes for Locally Stationary Functional Random Fields under Stochastic Sampling Design

open access: yesMathematics, 2022
Stute presented the so-called conditional U-statistics generalizing the Nadaraya–Watson estimates of the regression function. Stute demonstrated their pointwise consistency and the asymptotic normality.

Depth-based classification for functional data [PDF]

open access: yes, 2005
Classification is an important task when data are curves. Recently, the notion of statistical depth has been extended to deal with functional observations.

Identification of Granite Varieties from Colour Spectrum Data

open access: yesSensors, 2010
The granite processing sector of the northwest of Spain handles many varieties of granite with specific technical and aesthetic properties that command different prices in the natural stone market. Hence, correct granite identification and classification

Signature of Alzheimer’s Disease in Intestinal Microbiome: Results From the AlzBiom Study

open access: yesFrontiers in Neuroscience, 2022
BackgroundChanges in intestinal microbiome composition have been described in animal models of Alzheimer’s disease (AD) and AD patients. Here we investigated how well taxonomic and functional intestinal microbiome data and their combination with clinical

Use of functional cluster analysis of CPTU data for assessment of a subsoil rigidity

open access: yesStudia Geotechnica et Mechanica, 2018
This paper shows an example of the grouping of piezocone penetration test (CPTU) characteristics using functional data analysis, together with the results of clustering, in the form of a subsoil rigidity model.

Pattern Functional Dependencies for Data Cleaning [PDF]

open access: yes, 2020
Patterns (or regex-based expressions) are widely used to constrain the format of a domain (or a column), e.g., a Year column should contain only four digits, and thus a value like “1980-” might be a typo.

Kolmogorov Entropy for Convergence Rate in Incomplete Functional Time Series: Application to Percentile and Cumulative Estimation in High Dimensional Data

open access: yesEntropy, 2023
The convergence rate for free-distribution functional data analyses is challenging. It requires some advanced pure mathematics functional analysis tools.
