Rate-Constrained Trellis-Coded Quantization for Large-Scale Noisy Graph Signals

2022 · IEEE Communications Letters

We consider the issue of compressing large-scale noise-corrupted graph signals under a rate constraint, to tackle the communication resource limitations, from rate-distortion perspective. To guarantee the fidelity of the overall compression system for noisy graph …

Link-Information Augmented Twin Autoencoders for Network Denoising

2022 · IEEE Transactions on Cybernetics

Removing noisy links from an observed network is a task commonly required for preprocessing real-world network data. However, containing both noisy and clean links, the observed network cannot be treated as a trustworthy information source …

Stochastic Event-triggered Variational Bayesian Filtering

2022 · arXiv (Cornell University)

This paper proposes an event-triggered variational Bayesian filter for remote state estimation with unknown and time-varying noise covariances. After presetting multiple nominal process noise covariances and an initial measurement noise covariance, a variational Bayesian method …

Approximation and decomposition of attractors of a Hopfield neural network system

2024 · arXiv (Cornell University)

In this paper, the Parameter Switching (PS) algorithm is used to approximate numerically attractors of a Hopfield Neural Network (HNN) system. The PS algorithm is a convergent scheme designed for approximating attractors of an autonomous …
