Latent factor model for multivariate functional data
Li, R., & Xiao, L. (2023, September 4). BIOMETRICS, Vol. 9.
author keywords: covariance function; fPCA; functional data; model identifiability; penalized splines
TL;DR:
For multivariate functional data, a functional latent factor model is proposed, extending the traditional latent factor model for multivariate data and may provide a more parsimonious and interpretable characterization of the otherwise complex dependencies between the functions.

Fast Multilevel Functional Principal Component Analysis
Cui, E., Li, R., Crainiceanu, C. M., & Xiao, L. (2022, October 7). JOURNAL OF COMPUTATIONAL AND GRAPHICAL STATISTICS, Vol. 10.
author keywords: Functional principal component analysis; Mixed model equations; Multilevel models
TL;DR:
This work introduces fast multilevel functional principal component analysis (fast MFPCA), which scales up to high dimensional functional data measured at multiple visits, and achieves comparable estimation accuracy with the originalMFPCA.
