Stochastic Memristive Quaternion-Valued Neural Networks with Time Delays: An Analysis on Mean Square Exponential Input-to-State Stability

open access: yesMathematics, 2020
In this paper, we study the mean-square exponential input-to-state stability (exp-ISS) problem for a new class of neural network (NN) models, i.e., continuous-time stochastic memristive quaternion-valued neural networks (SMQVNNs) with time delays ...

On Symmetrized Stochastic Harmonically Convexity and Hermite–Hadamard Type Inequalities

open access: yesAxioms, 2022
Throughout this study, the concept of symmetrized harmonically convex stochastic processes will be discussed in further detail. Some certain characterizations for symmetrized harmonically convex stochastic processes are discussed that use Hermite ...

Exponential Stability in Mean Square for Neutral Stochastic Partial Functional Differential Equations with Impulses

open access: yesJournal of Applied Mathematics, 2013
We discuss the exponential stability in mean square of mild solution for neutral stochastic partial functional differential equations with impulses. By applying impulsive Gronwall-Bellman inequality, the stochastic analytic techniques, the fractional ...

Stability analysis of stochastic and random systems in the Lyapunov sense

open access: yesResults in Control and Optimization, 2021
Lyapunov approach plays a vital role in addressing the issue of stability in deterministic and random (stochastic) systems. This paper is involved in the study of stability of linear and nonlinear systems perturbed by a standard Brownian motion, random ...

Multitask Diffusion Adaptation over Networks [PDF]

open access: yes, 2013
Adaptive networks are suitable for decentralized inference tasks, e.g., to monitor complex natural phenomena. Recent research works have intensively studied distributed optimization problems in the case where the nodes have to estimate a single optimum ...

Mean-square exponential input-to-state stability of stochastic quaternion-valued neural networks with time-varying delays

open access: yesAdvances in Difference Equations, 2021
In this paper, we first consider the stability problem for a class of stochastic quaternion-valued neural networks with time-varying delays. Next, we cannot explicitly decompose the quaternion-valued systems into equivalent real-valued systems; by using ...

Structure of exotic three-body systems

open access: yes, 2005
The classification of large halos formed by two identical particles and a core is systematically addressed according to interparticle distances. The root-mean-square distances between the constituents are described by universal scaling functions obtained

Stability Analysis of Cohen–Grossberg Neural Networks with Random Impulses

open access: yesMathematics, 2018
The Cohen and Grossberg neural networks model is studied in the case when the neurons are subject to a certain impulsive state displacement at random exponentially-distributed moments.

Stability of matrix factorization for collaborative filtering [PDF]

open access: yes, 2012
We study the stability vis a vis adversarial noise of matrix factorization algorithm for matrix completion. In particular, our results include: (I) we bound the gap between the solution matrix of the factorization method and the ground truth in terms of ...
