The phrase "function fitting" is correct and usable in written English.
It is typically used in mathematics or computer programming and refers to the approximation of a mathematical function, such as a curve or polynomial, based on given data points. For example, "The process of function fitting allowed us to accurately predict future sales trends."
The SPLINE-curve fitting is a global function fitting to smooth discrete data.
Using the modified fitting points and the improved Gaussian function fitting method, the cumulative grain-size distribution curve and the probability density curve of the mixed-size sediments were obtained.
"Efficient analytical fragility function fitting using dynamic structural analysis". Earthquake Spectra, (in press).
We develop a fully Bayesian method to analyze the single index models, including variable selection, the index vector estimation and the link function fitting with free-knot splines.
A structured representation on genetic algorithms for non-linear function fitting or STROGANOFF is the chosen architecture for genetic programming implementation.
A main advantage of this method is that it can increase the proportion of support vectors to the whole samples and uniformity of support vectors in space dramatically and it requires less samples in function fitting.
The proposed method as well as the relevant techniques of data normalization and parameters optimization of kernel function model of support vector machine, is used in the structural failure function fitting.
The results from the neural network fittings are then compared with experimental values, previous results calculated by Bauschlicher and Langhoff and the ones obtained by using of extended Rydberg function fitting.
Well-established rational-function fitting techniques are used to set the poles, while residues are determined by enforcing the boundary conditions in the least-squares sense at the nodes of rational Gauss Chebyshev quadrature rules.
Early ionospheric modeling methods were mostly based on function-fitting techniques such as those for spherical harmonics (Schaer, 1999), the broadcasting ionosphere model (Klobuchar, 1987) and polynomial functions.
This new result shows that such Galerkin bases not only retain exponential convergence but expedient function-fitting properties too, in much the same way as the Jacobi polynomials themselves.
