A Fast Weighted Fuzzy C-Medoids Clustering for Time Series Data Based on P-Splines [PDF]
Sensors, 2022 The rapid growth of digital information has produced massive amounts of time series data on rich features and most time series data are noisy and contain some outlier samples, which leads to a decline in the clustering effect. To efficiently discover the

Out-of-Sample Prediction in Multidimensional P-Spline Models
Mathematics, 2021 The prediction of out-of-sample values is an interesting problem in any regression model. In the context of penalized smoothing using a mixed-model reparameterization, a general framework has been proposed for predicting in additive models but without ...

Semilocal smoothihg S-splines [PDF]
Компьютерные исследования и моделирование, 2010 Semilocal smoothing splines or S-splines from class C p are considered. These splines consist of polynomials of a degree n, first p + 1 coefficients of each polynomial are determined by values of the previous polynomial and p its derivatives at the point

Twenty years of P-splines [PDF]
, 2015 P-splines first appeared in the limelight twenty years ago. Since then they have become popular in applications and in theoretical work. The combination of a rich B-spline basis and a simple difference penalty lends itself well to a variety of ...
