Overcoming Tight Constraints in Soft Happy Colouring
Mohammad Hadi Shekarriz, Asef Nazari, Dhananjay Thiruvady
The Soft Happy Colouring (SHC) problem, a mathematical framework for identifying homophilic network structures, seeks to maximise the number of -happy vertices, i.e., vertices…
Multiobjective Model Predictive Control for Residential Demand Response Management Under Uncertainty
Guan-Ting Lin, Wei-Yu Chiu, Chien-Feng Wu +2
Residential users in demand response programs must balance electricity costs and user dissatisfaction under real-time pricing. This study proposes a multiobjective model predictive…
ALFA: A Safe-by-Design Approach to Mitigate Quishing Attacks Launched via Fancy QR Codes
Muhammad Wahid Akram, Keshav Sood, Muneeb Ul Hassan +1
Phishing with Quick Response (QR) codes is termed as Quishing. The attackers exploit this method to manipulate individuals into revealing their confidential data. Recently, we see…
Finding happiness by evolutionary algorithms
Mohammad Hadi Shekarriz, Dhananjay Thiruvady, Asef Nazari
A recent line of research concerns the problem of soft happy colouring (SHC), which requires that a partially coloured graph be extended to a complete colouring to maximise local a…
Audio Physical Dynamics Inspired Deepfake Detection for Voice Authentication Systems
Alireza Mohammadi, Keshav Sood, Dhananjay Thiruvady +1
Voice authentication systems deployed at the network edge face dual threats: a) sophisticated deepfake synthesis attacks and b) control-plane poisoning in distributed federated lea…
Bayesian Network Fusion of Large Language Models for Sentiment Analysis
Rasoul Amirzadeh, Dhananjay Thiruvady, Fatemeh Shiri
Large language models (LLMs) continue to advance, with an increasing number of domain-specific variants tailored for specialised tasks. However, these models often lack transparenc…
