Low‐rank approximation for smoothing spline via eigensystem truncation
Stat, 2021 Smoothing splines provide a powerful and flexible means for nonparametric estimation and inference. With a cubic time complexity, fitting smoothing spline models to large data is computationally prohibitive. In this paper, we use the theoretical optimal eigenspace to derive a low‐rank approximation of the smoothing spline estimates. We develop a method

BPX preconditioners for isogeometric analysis using (truncated) hierarchical B-splines [PDF]
Computer Methods in Applied Mechanics and Engineering, 2021 We present the construction of additive multilevel preconditioners, also known as BPX preconditioners, for the solution of the linear system arising in isogeometric adaptive schemes with (truncated) hierarchical B-splines. We show that the locality of hierarchical spline functions, naturally defined on a multilevel structure, can be suitably exploited ...

Pemodelan Regresi Nonparametrik Spline Truncated pada Data Longitudinal
Inferensi, 2021 Saat ini pendekatan regresi nonparametrik banyak mendapat perhatian dari para peneliti, dikarenakan memiliki fleksibilitas yang tinggi dan tidak tergantung pada asumsi bentuk kurva regresi. Spline truncated adalah salah satu model dalam regresi nonparametrik yang sering digunakan, karena mampu menangani data yang perilakunya berubah-ubah pada sub-sub ...

Majalah Ilmiah Matematika dan Statistika, 2022 Tuberculosis is a bacterial infection caused by Mycobacterium tuberculosis. Transmission of tuberculosis (TBC) can occur due to environmental factors and community behavior. West Java is Indonesia's province with the highest number of tuberculosis cases.

Remarks on Poincaré and interpolation estimates for Truncated Hierarchical B-splines
Mathematical Models and Methods in Applied Sciences, 2021 This paper should be considered as an addendum to [A. Buffa and C. Giannelli, Adaptive isogeometric methods with hierarchical splines: Error estimator and convergence, Math. Models Methods Appl. Sci. 26 (2016) 1–25] and [A. Buffa and C. Giannelli, Adaptive isogeometric methods with hierarchical splines: Optimality and convergence rates, Math.
