Using an Opportunity Matrix to Select Centers for RBF Neural Networks
When designed correctly, radial basis function (RBF) neural networks can approximate mathematical functions to any arbitrary degree of precision. Multilayer perceptron (MLP) neural networks are also universal function approximators, but RBF neural ...

Zeros of Approximate Functional Approximations [PDF]
The gN(s) are of interest as approximations to the Riemann zeta function. Let s = or + it. In [1], it was shown that for t sufficiently large, gi(s) and g2(s) have their zeros on the critical line ar = 2. After encountering analytical difficulties in attempting to extend this theorem to further N, the calculations described below were undertaken.

Linear and Quadratic Interpolators Using Truncated-Matrix Multipliers and Squarers
This paper presents a technique for designing linear and quadratic interpolators for function approximation using truncated multipliers and squarers. Initial coefficient values are found using a Chebyshev-series approximation and then adjusted through ...

On the Universally Optimal Activation Function for a Class of Residual Neural Networks
While non-linear activation functions play vital roles in artificial neural networks, it is generally unclear how the non-linearity can improve the quality of function approximations.

The paper considers the slope flow simulation and the problem of finding the optimal parameter values of this mathematical model. The slope flow is modeled using the finite volume method applied to the Reynolds-averaged Navier–Stokes equations with ...

Approximate Atomic Green Functions [PDF]
In atomic and many-particle physics, Green functions often occur as propagators to formally represent the (integration over the) complete spectrum of the underlying Hamiltonian. However, while these functions are very crucial to describing many second- and higher-order perturbation processes, they have hardly been considered and classified for complex ...

THE SOLUTION OF THE APPROXIMATION PROBLEM OF NONLINEAR DEPENDANCES USING ARTIFICIAL NEURAL NETWORKS
The paper discusses issues connected with the use of an artificial neural network (ANN) to approximate the experimental data. One of the problems in the development of the ANN is the choice of an appropriate activation function for neurons of the hidden ...

Approximations to Kelvin Functions [PDF]
While preparing a digital computer program to examine the behavior of largetaper hub flanges, it was found necessary to use approximations to the Kelvin functions ber x, bei x, ker x, and kei x, and to their first derivatives. To obtain full machine accuracy, the approximations were required to be correct to nine significant figures.
