Machine learning and geophysical inversion — A numerical study
The Leading Edge, 2019As geophysicists, we are trained to conceptualize geophysical problems in detail. However, machine learning algorithms are more difficult to understand and are often thought of as simply “black boxes.” A numerical example is used here to illustrate the ...

An overrelaxation for a numerical inverse of a constant
Communications of the ACM, 1980When division is performed by a power series implementation with additions, subtractions, digit shifts, and multiplications, the convergence rate of the power series is important in practical application. Particularly if the rate of the power series is close to one, the convergence is slow and therefore a special method to accelerate the convergence is

Numerical Inversion of a Characteristic Function
Biometrika, 1973SUMMARY A method is described for finding a bound on the error when a version of the usual characteristic function inversion formula is evaluated by numerical integration. The method is applied to the calculation of the distribution function of a quadratic form in normal random variables.

Numerical Approach to Inverse Flight Dynamics
Journal of Guidance, Control, and Dynamics, 1997We develop a general numerical approach to inverse problems of vehicle dynamics, suitable for both e xed- and rotating-wing aircrafts. The formulation is based on an energy-preserving e nite element in time for rigid body dynamics that ensures unconditional stability according to the energy method.

A Note on the Numerical Inversion of the Laplace Transform
2006The aim of this paper is to show that the recently developed high performance divide and conquer algorithm for finding trigonometric sums can be applied to improve the performance of the Talbot's method for the numerical inversion of the Laplace Transform on modern computer architectures including shared memory parallel computers. We also show

Numerical Stability in an Inverse Scattering Problem
SIAM Journal on Numerical Analysis, 1980The main result of this paper is a stability theorem for a certain class of difference algorithms designed to give approximate solutions of a model inverse scattering problem in one dimension. This stability result guarantees the convergence of the approximate solutions to the exact solution of the problem as the grid of the difference scheme is ...
