A Deep Learning Approach for Predicting Spatiotemporal Dynamics From Sparsely Observed Data

open access: yesIEEE Access, 2021
In this paper, we consider the problem of learning prediction models for spatiotemporal physical processes driven by unknown partial differential equations (PDEs).

Construction of Cubic Timmer Triangular Patches and its Application in Scattered Data Interpolation

open access: yesMathematics, 2020
This paper discusses scattered data interpolation by using cubic Timmer triangular patches. In order to achieve C1 continuity everywhere, we impose a rational corrected scheme that results from convex combination between three local schemes.

On the Constrained Solution of RBF Surface Approximation

open access: yesMathematics, 2022
In this contribution, a scattered data approximation problem, chosen from the literature and using the Radial Basis Function (RBF) approach, is considered for the application of point cloud modelling.

Cubic Bézier-Like Triangular Patches for Rainfall Scattered Data Interpolation and Visualization [PDF]

open access: yesITM Web of Conferences
Scattered data interpolation plays an important role in computer graphics and scientific visualization. This method can be used to interpolate any regular or irregular data sets. For instance, rainfall distribution is an example of an irregular data that

Construction of new cubic Bézier-like triangular patches with application in scattered data interpolation

open access: yesAdvances in Difference Equations, 2020
This paper discusses the functional scattered data interpolation to interpolate the general scattered data. Compared with the previous works, we construct a new cubic Bézier-like triangular basis function controlled by three shape parameters.

Interpolation and scattered data fitting on manifolds using projected Powell–Sabin splines [PDF]

open access: yes, 2008
We present methods for either interpolating data or for fitting scattered data on a two-dimensional smooth manifold. The methods are based on a local bivariate Powell-Sabin interpolation scheme, and make use of a family of charts {(Uξ , ξ)}ξ∈ satisfying ...

The 1-D Hermite Shepard and MLS method [PDF]

open access: yesMathematics and Computational Sciences, 2021
In many applications, one encounters the problem of approximating 1-D curve and 2-D surfaces from data given on a set of scattered points. Meshless methods strategy is based on some facts: (1) deleting mesh generation and re-meshing, (2) raising smooth ...

Image reconstruction from scattered Radon data by weighted positive definite kernel functions [PDF]

open access: yes, 2018
We propose a novel kernel-based method for image reconstruction from scattered Radon data. To this end, we employ generalized Hermite–Birkhoff interpolation by positive definite kernel functions. For radial kernels, however, a straightforward application

Scattered Data Interpolation: Tests of Some Method [PDF]

open access: yesMathematics of Computation, 1982
This paper is concerned with the evaluation of methods for scattered data interpolation and some of the results of the tests when applied to a number of methods. The process involves evaluation of the methods in terms of timing, storage, accuracy, visual pleasantness of the surface, and ease of implementation.
