Asymptotics for penalized additive B-spline regression [PDF]

open access: yes, 2011
This paper is concerned with asymptotic theory for penalized spline estimator in bivariate additive model. The focus of this paper is put upon the penalized spline estimator obtained by the backfitting algorithm.

Analysis-suitable adaptive T-mesh refinement with linear complexity [PDF]

open access: yes, 2014
We present an efficient adaptive refinement procedure that preserves analysis-suitability of the T-mesh, this is, the linear independence of the T-spline blending functions.

Boosting Additive Models using Component-wise P-Splines [PDF]

open access: yes, 2007
We consider an efficient approximation of Bühlmann & Yu’s L2Boosting algorithm with component-wise smoothing splines. Smoothing spline base-learners are replaced by P-spline base-learners which yield similar prediction errors but are more advantageous ...

BMICA-independent component analysis based on B-spline mutual information estimator [PDF]

open access: yes, 2012
The information theoretic concept of mutual information provides a general framework to evaluate dependencies between variables. Its estimation however using B-Spline has not been used before in creating an approach for Independent Component Analysis. In

Polynomial spline-approximation of Clarke's model [PDF]

open access: yes, 2004
We investigate polynomial spline approximation of stationary random processes on a uniform grid applied to Clarke's model of time variations of path amplitudes in multipath fading channels with Doppler scattering. The integral mean square error (MSE) for

Smoothing under Diffeomorphic Constraints with Homeomorphic Splines [PDF]

open access: yes, 2010
In this paper we introduce a new class of diffeomorphic smoothers based on general spline smoothing techniques and on the use of some tools that have been recently developed in the context of image warping to compute smooth diffeomorphisms.

A Hermite interpolatory subdivision scheme for $C^2$-quintics on the Powell-Sabin 12-split [PDF]

open access: yes, 2014
In order to construct a $C^1$-quadratic spline over an arbitrary triangulation, one can split each triangle into 12 subtriangles, resulting in a finer triangulation known as the Powell-Sabin 12-split.

Surgery of spline-type and molecular frames [PDF]

open access: yes, 2009
We prove a result about producing new frames for general spline-type spaces by piecing together portions of known frames. Using spline-type spaces as models for the range of certain integral transforms, we obtain results for time-frequency decompositions

Volumetric Untrimming: Precise decomposition of trimmed trivariates into tensor products

open access: yes, 2019
3D objects, modeled using Computer Aided Geometric Design tools, are traditionally represented using a boundary representation (B-rep), and typically use spline functions to parameterize these boundary surfaces.

Examination of the Circle Spline Routine [PDF]

open access: yes, 1985
The Circle Spline routine is currently being used for generating both two and three dimensional spline curves. It was developed for use in ESCHER, a mesh generating routine written to provide a computationally simple and efficient method for building ...
