Chúc mừng sinh viên nhóm nghiên cứu UiTiOt đã có bài báo được chấp nhận tại Hội nghị quốc tế International Conference on Intelligent Aerial Access and Applications (IAAA 2026) được tổ chức vào 27-29/7/2026 tại Thành phố Hồ Chí Minh, Việt Nam.Bài báo: DT-MARL-UAV: Safe Multi-UAV Trajectory Coordination via Digital Twin-Assisted Multi-Agent Reinforcement LearningSinh viên thực hiện:- Nguyễn Dương Hoàng Phúc – MMTT2022 – Tác giả chính- Phan Văn Tài – MMTT2022 – Đồng tác giảGiảng viên hướng dẫn:- TS. Huỳnh Văn Đặng- ThS. Đặng Lê Bảo ChươngTóm tắt: This paper presents DT-MARL-UAV, a framework for safe multi-UAV trajectory coordination in shared airspaces. The proposed method uses multi-agent proximal policy optimization (MAPPO) under the centralized training with decentralized execution (CTDE) paradigm to optimize multi-agent trajectories, conditioned on local observations of velocity, relative goal displacement, neighboring agents, and obstacles. A digital twin (DT)-based predictive safety shield is also used to perform rollforward simulations and blend artificial potential field (APF) recovery corrections with the learned policy output when a violation is predicted. Experiments in multi-UAV navigation scenarios of increasing difficulty show that DT-MARL-UAV reduces collision counts by 99% and maintains a 92-97% success rate compared to the MAPPO-only baseline, demonstrating robust and consistent safety verification across multiple random seeds.Thông tin Hội nghị: IAAA 2026 is co-hosted by Ho Chi Minh City University of Technology (HCMUT), Vietnam National University of Agriculture (VNUA), Hanoi University of Mining and Geology (HUMG), and FPT University Da Nang (FUDN) and will be held during 27-29 July 2026 in Ho Chi Minh City, Vietnam.IAAA 2026 is an international academic exchange forum aimed at sharing experiences and discussing innovations, advancements, and future trends revolving around the integration of unmanned aerial vehicles (UAVs/Drones), artificial intelligence, embedded systems, and aerial communication networks. The conference highlights practical applications such as remote sensing, precision agriculture, and environmental monitoring, while addressing challenges in communication performance and network security. All accepted papers will be published by Springer in the Lecture Notes in Networks and Systems (LNNS) series, which is indexed by SCOPUS.Trang chủ Hội nghị: https://cse.hcmut.edu.vn/iaaa2026/Thông tin chi tiết tại: https://www.facebook.com/share/p/1DFAA3zZJu/ Đông Xanh - Cộng tác viên truyền thông Trường Đại học Công nghệ Thông tin
