A Second-Order Perceptron Algorithm [PDF]
SIAM Journal on Computing, 2002 Summary: Kernel-based linear-threshold algorithms, such as support vector machines and Perceptron-like algorithms, are among the best available techniques for solving pattern classification problems. In this paper, we describe an extension of the classical Perceptron algorithm, called second-order Perceptron, and analyze its performance within the ...

Journal of Nigerian Society of Physical Sciences, 2023 It is a known fact that in most cases, to integrate an oscillatory problem, higher order A-stable methods are often needed. This is because such problems are characterized by stiffness, chaos and damping, thus making them tedious to solve.

Exponential Time Differencing Algorithm for Pulse-Coupled Hodgkin-Huxley Neural Networks
Frontiers in Computational Neuroscience, 2020 The exponential time differencing (ETD) method allows using a large time step to efficiently evolve stiff systems such as Hodgkin-Huxley (HH) neural networks.

Second-Order Weak Approximations of CKLS and CEV Processes by Discrete Random Variables
Mathematics, 2021 In this paper, we construct second-order weak split-step approximations of the CKLS and CEV processes that use generation of a three−valued random variable at each discretization step without switching to another scheme near zero, unlike other known ...

Second-order Darboux displacements [PDF]
Journal of Physics A: Mathematical and General, 2003 The potentials for a one dimensional Schroedinger equation that are displaced along the x axis under second order Darboux transformations, called 2-SUSY invariant, are characterized in terms of a differential-difference equation. The solutions of the Schroedinger equation with such potentials are given analytically for any value of the energy.

Continuous Adaptive Finite Reaching Time Control and Second-Order Sliding modes [PDF]
, 2013 This paper focuses on the design of adaptive finite reaching time control for first- and second-order dynamic systems with perturbation terms given in a regressive form. The uncertainties considered here are assumed to be bounded with unknown bounds. The

A second order logic of existence [PDF]
, 1969 Publisher's, offprint versionA. N. Prior in [9] has suggested an approach towards a second order logic of existence where, following medieval logicians, we distinguish “between predicates (like ‘is red’, ‘is hard’, etc.) which entail existence, and ...
