Symbolic computation in nonlinear control system analysis & design

, 1996
Symbolic computation, also known as computer algebra, is a powerful tool in solving tough and intricate problems in applied mathematics. We present a closely tied set of symbolic computation functions, together called the NON~CON package that solves some

On the Use of Resultant-Based Frequency-Sweeping Approaches to Construct Stability Charts for Systems With Two Delays

IEEE Access
The resultant-based frequency-sweeping approach is appealing for creating a stability map to study stability robustness against delay uncertainties. It relies on converting the system’s transcendental characteristic function into a polynomial form

Monomial resolutions for efficient computation of simplicial homology

, 2019
We propose algorithms based on monomial resolution theory for simplicial homology computation. We explore some alternatives that can either be used as a preprocessing step for homology computation or as alternatives to the usual linear algebra approach ...

Enhancing generalized spectral clustering with embedding Laplacian graph regularization

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract An enhanced generalised spectral clustering framework that addresses the limitations of existing methods by incorporating the Laplacian graph and group effect into a regularisation term is presented. By doing so, the framework significantly enhances discrimination power and proves highly effective in handling noisy data.

LLM‐Powered Data Synthesis on Blockchain for Fusion Isomerism Learning in Heterogeneous Federated Systems

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Severe data starvation, architectural heterogeneity and Byzantine vulnerabilities fundamentally impede the deployment of robust multiclass classification models in decentralised edge environments. To address these intertwined challenges, we propose fusion isomerism learning (FusionIL), a secure and domain‐agnostic framework that ...
