V-Spline: An Adaptive Smoothing Spline for Trajectory Reconstruction [PDF]

open access: yesSensors, 2021
Trajectory reconstruction is the process of inferring the path of a moving object between successive observations. In this paper, we propose a smoothing spline—which we name the V-spline—that incorporates position and velocity information and a penalty ...

Novel Information-Driven Smoothing Spline Linearization Method for High-Precision Displacement Sensors Based on Information Criterions [PDF]

open access: yesSensors, 2023
A noise-resistant linearization model that reveals the true nonlinearity of the sensor is essential for retrieving accurate physical displacement from the signals captured by sensing electronics.

Application of Smoothing Spline in Determining the Unmanned Ground Vehicles Route Based on Ultra-Wideband Distance Measurements [PDF]

open access: yesSensors, 2022
Unmanned ground vehicles (UGVs) are technically complex machines to operate in difficult or dangerous environmental conditions. In recent years, there has been an increase in research on so called “following vehicles”. The said concept introduces a guide—

Principle of Duality in Cubic Smoothing Spline

open access: yesMathematics, 2020
Fitting a cubic smoothing spline is a typical smoothing method. This paper reveals a principle of duality in the penalized least squares regressions relating to the method.

Use of Two Smoothing Parameters in Penalized Spline Estimator for Bi-variate Predictor Non-parametric Regression Model [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2020
Penalized spline criteria involve the function of goodness of fit and penalty, which in the penalty function contains smoothing parameters. It serves to control the smoothness of the curve that works simultaneously with point knots and spline degree. The

Spline estimator and its asymptotic properties in multiresponse nonparametric regression model [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2020
In applications, we often meet the problem where more than one response variable is observed at several values of predictor variables, and these responses are correlated with each other.

Quantile smoothing splines [PDF]

open access: yesBiometrika, 1994
Summary: Although nonparametric regression has traditionally focused on the estimation of conditional mean functions, nonparametric estimation of conditional quantile functions is often of substantial practical interest. We explore a class of quantile smoothing splines, defined as solutions to \[ \min_{g\in {\mathcal G}}\sum \rho_ \tau \{y_ i- g(x_ i)\}

Effects of different seasonal fitting methods on the spatial distribution characteristics of common mode errors

open access: yesFrontiers in Earth Science, 2023
This study investigated the effects of various seasonal fitting techniques on the spatial distribution of the common mode errors taking the coordinate time series of the continuous GPS reference stations of the Crustal Movement Observation Network of ...

Smoothing Splines for Discontinuous Signals

open access: yesJournal of Computational and Graphical Statistics, 2023
Smoothing splines are twice differentiable by construction, so they cannot capture potential discontinuities in the underlying signal. In this work, we consider a special case of the weak rod model of Blake and Zisserman that allows for discontinuities penalizing their number by a linear term.

Penalized spline estimator with multi smoothing parameters in bi-response multi-predictor nonparametric regression model for longitudinal data [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2020
Penalized spline estimators that depend on a smoothing parameter is one type of estimator used in the estimation regression curve in nonparametric regression.
