On Quasi-Monotone Stochastic Variational Inequalities with Applications

Axioms
This paper studies an efficient method for solving stochastic optimization problems formulated as stochastic variational inequalities with a quasi-monotone operator, where the cost function extends the classical monotone and pseudomonotone operators. Our

Research and application of weak fault diagnosis method based on asymmetric potential stochastic resonance

Measurement + Control, 2019
Because fault characteristics are often difficult to extract from a strong noise background, it is essential for mechanical fault diagnosis to extract a weak characteristic signal with a very small signal-to-noise ratio from a noisy interference ...

Stochastic Response of Composite Post Insulators under Seismic Excitation

Buildings
Composite post insulators are crucial facilities in substations and are prone to significant damage during seismic disasters. However, existing research lacks seismic motion models suitable for power facilities and rarely involves stochastic models ...

Stochastic Steffensen method

Computational Optimization and Applications
Is it possible for a first-order method, i.e., only first derivatives allowed, to be quadratically convergent? For univariate loss functions, the answer is yes -- the Steffensen method avoids second derivatives and is still quadratically convergent like Newton method.
