Second Order Derivatives for Network Pruning: Optimal Brain Surgeon
 Advances in Neural Information Processing Systems 5
, 1993
"... We investigate the use of information from all second order derivatives of the error function to perform network pruning (i.e., removing unimportant weights from a trained network) in order to improve generalization and increase the speed of further training. ..."

On the second order derivatives of convex functions on the Heisenberg group
 Ann. Scuola Norm. Sup. Pisa Cl. Sci
"... A classical result of Aleksandrov asserts that convex functions inR n are twice differentiable a.e., and a first step to prove it is to show that these functions have second order distributional derivatives which are measures, see [3, pp. 239245]. On the Heisenberg group, and more generally in Carn ..."

On Discretization of Secondorder Derivatives in Smoothed Particle Hydrodynamics
"... Abstractâ€”Discretization of spatial derivatives is an important issue in meshfree methods especially when the derivative terms contain nonlinear coefficients. In this paper, various methods used for discretization of secondorder spatial derivatives are investigated in the context of Smoothed Partic ..."

On discontinuous Galerkin discretizations of secondorder derivatives
"... Some properties of a Local discontinuous Galerkin (LDG) algorithm are demonstrated for the problem of evaluting a second derivative g = fxx for a given f. (This is a somewhat unusual problem, but it is useful for understanding the initial transient response of an algorithm for diffusion equations.) ..."

ClassicCurvature: A Second Order Derivatives Based Approach
"... Abstract: Given a signal data in either one or in multiple dimensions, and given a model function fitted to the signal data, it is possible to calculate the curvature through the computation of all of the second order derivatives of the model function using rigorous calculus methodologies. This manu ..."

Jump detection in regression surfaces using both firstorder and secondorder derivatives
 Journal of Computational and Graphical Statistics
, 2007
"... We consider the problem of detecting jump location curves of regression surfaces. In the literature, most existing methods detect jumps in regression surfaces based on estimation of either the firstorder or the secondorder derivatives of regression surfaces. Methods based on the firstorder deriva ..."

Second Order Derivatives, Newton Method, Application to Shape Optimization
, 1995
"... We describe a Newton method applied to the evaluation of a critical point of a total energy associated to a shape optimization problem. The key point of this methods is the Hessian of the shape functional. We give an expression of the Hessian as well as the relation with the secondorder Eulerian s ..."
