Low-complexity variable step-size sign algorithm based on Weibull distribution function
The performance of the traditional second-order statistics based channel estimation methods degrade seriously in the presence of impulsive noises.In order to deal with this problem,a Weibull distribution function based variable step-size sign algorithm ...

Solution for nonlinear Duffing oscillator using variable order variable stepsize block method
Real life phenomena found in various fields such as engineering, physics, biology and communication theory can be modeled as nonlinear higher order ordinary differential equations, particularly the Duffing oscillator. Analytical solutions for these differential equations can be time consuming whereas, conventional numerical solutions may lack accuracy.

On the Stability of Variable Stepsize Rational Approximations of Holomorphic Semigroups [PDF]
We consider variable stepsize time approximations of holomorphic semigroups on general Banach spaces. For strongly A ( θ ) {\text {A}}(\theta ) -acceptable rational functions a general stability theorem is proved, which does not impose any constraint on the ratios between stepsizes.

Tracking the gradients using the Hessian: A new look at variance reducing stochastic methods
Our goal is to improve variance reducing stochastic methods through better control variates. We first propose a modification of SVRG which uses the Hessian to track gradients over time, rather than to recondition, increasing the correlation of the ...
