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

, 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

KOLMOGOROV'S SPLINE NETWORK [PDF]

IEEE Transactions on Neural Networks, 2003
In this paper, an innovative neural-network architecture is proposed and elucidated. This architecture, based on the Kolmogorov's superposition theorem (1957) and called the Kolmogorov's spline network (KSN), utilizes more degrees of adaptation to data than currently used neural-network architectures (NNAs).

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

, 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.

New approach for solution of volterra integral equations using spline quasi-interpolant [PDF]

Journal of Hyperstructures, 2019
In this paper, we present quadratic rule for approximate solution of integrals using spline quasi-interpolant. The methodis applied for solving the linear Volterra integral equations. Also the convergence analysis of the method is given.

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

, 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

L-Splines

Numerische Mathematik, 1967
In this paper, we study the problem of unique interpolation and approximation by a class of spline functions,L-splines, containing as special cases the deficient and generalized spline functions ofAhlberg, Nilson, andWalsh [3, 5, 6], the Chebyshevian spline functions ofKarlin andZiegler [27], and the piecewise Hermite polynomial functions, as ...

Comparison Between T-Spline Surface and NURBS Surface [PDF]

Engineering and Technology Journal, 2015
This research uses T-spline for surface modeling and compares it with NURBS modeling to get the best modeling points between the two methods. The comparison will be through surface analysis and manufacturing process.T-Splines surfaces typically have 50 ...

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

, 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.

Verification of the Spline Method and its Application to Curvilinear Objects

Technical Transactions, 2019
Two methods of interpolation are presented in this article: interpolation with the help of orthogonal polynomials and interpolation on a cubic spline path (with the help of glued-together functions).

Generalized additive models as an alternative approach to the modelling of the tree height-diameter relationship

Journal of Forest Science, 2015
Generalized additive models were tested using three types of smoothing functions as an alternative for modelling the height curve. The models were produced for 23 forest stands of Norway spruce (Picea abies [L.] Karst.) in the territory of the Training ...
