Ranking-Augmented On-Policy Optimization with Adaptive Advantage-Normalization for Constrained Control
Md Ragib Rownak, Sidra Ghayour Bhatti, Qadeer Ahmed
This paper analyzes the boundedness and feasibility properties of Advantage-Ranked Group Relative Policy Optimization (A-GRPO), a ranking-augmented, critic-free policy gradient met…
Sequence Aware SAC Control for Engine Fuel Consumption Optimization in Electrified Powertrain
Wafeeq Jaleel, Md Ragib Rownak, Athar Hanif +2
As hybrid electric vehicles (HEVs) gain traction in heavy-duty trucks, adaptive and efficient energy management is critical for reducing fuel consumption while maintaining battery…
Multi-Stage Knowledge-Distilled VGAE and GAT for Robust Controller-Area-Network Intrusion Detection
Robert Frenken, Sidra Ghayour Bhatti, Hanqin Zhang +1
The Controller Area Network (CAN) protocol is a standard for in-vehicle communication but remains susceptible to cyber-attacks due to its lack of built-in security. This paper pres…
Improving Q-Learning for Real-World Control: A Case Study in Series Hybrid Agricultural Tractors
Hend Abououf, Sidra Ghayour Bhatti, Qadeer Ahmed
The variable and unpredictable load demands in hybrid agricultural tractors make it difficult to design optimal rule-based energy management strategies, motivating the use of adapt…
KD-GAT: Combining Knowledge Distillation and Graph Attention Transformer for a Controller Area Network Intrusion Detection System
Robert Frenken, Sidra Ghayour Bhatti, Hanqin Zhang +1
The Controller Area Network (CAN) protocol is widely adopted for in-vehicle communication but lacks inherent security mechanisms, making it vulnerable to cyberattacks. This paper i…
