On stable numerical differentiation

Kansas State University(堪萨斯州立大学)

N. S. Hoang, A. G. Ramm

AI总结:

基于正则化Volterra方程,提出两种数值微分方法,并通过数值实验验证其有效性和与变分正则化方法相比的竞争力。

摘要:

基于正则化Volterra方程,考虑了两种不同的数值微分方法。第一种方法涉及求解正则化Volterra方程,而第二种方法基于求解正则化Volterra方程的离散版本。数值实验表明,这些方法在稳定计算含噪函数导数方面是有效的,并且与变分正则化方法相比具有竞争力。

英文摘要:

Based on a regularized Volterra equation, two different approaches for numerical differentiation are considered. The first approach consists of solving a regularized Volterra equation while the second approach is based on solving a disretized version of the regularized Volterra equation. Numerical experiments show that these methods are efficient and compete favorably with the variational regularization method for stable calculating the derivatives of noisy functions.
