Best Paper Award, the 22nd International Conference on Algorithms and Architectures for Parallel Processing (ICA3PP’2022)

Dr Wenjuan Li and her research collaborators from the Aalborg University won the Best Paper Award in the 22nd International Conference on Algorithms and Architectures for Parallel Processing (ICA3PP) 2022 for their paper "EnergyCIDN: Enhanced Energy-aware Challenge-based Collaborative Intrusion Detection in Internet of Things". ICA3PP is one of the most famous events of the world that covers the many dimensions of parallel algorithms and architectures, encompassing fundamental theoretical approaches, practical experimental projects, and commercial components and systems. Due to the structure, distributed intrusion detection may suffer from the insider threats, where a malicious node can share false information to influence the network performance. Dr Li's research team developed EnergyCIDN, an enhanced challenge-based collaborative intrusion detection network by adopting an energy-aware trust management model against advanced insider attacks. The proposed scheme can measure the reputation of an internal node by considering energy consumption, which is especially effective in an IoT environment. The results demonstrated that the proposed approach can be more robust against advanced insider attacks, compared with similar trust management schemes.

Best Paper Award in the International Workshop on Advanced Image Technology 2022

Prof. Kenneth Lam and our PhD student, Mr Jun Xiao, won the Best Paper Award in the International Workshop on Advanced Image Technology (IWAIT) 2022 for their paper “Multi-level Feature Aggregation Network for High Dynamic Range Imaging”. The International Workshop on Advanced Image Technology is a well-known international event that gathers researchers, professors, students and interested persons in the field of advanced image technology. Modern digital cameras typically cannot capture the whole range of illumination, due to the limited sensing capability of sensor devices. High dynamic range (HDR) imaging aims to generate images with a larger range of illumination by merging multiple low-dynamic range (LDR) images with different exposure times. However, when the images are captured in dynamic scenes, existing methods unavoidably produce undesirable artifacts and distorted content. In this paper, the research team proposed a multi-level feature aggregation network, based on the Laplacian pyramid, to address this issue for HDR imaging. The proposed method progressively aggregates non-overlapping frequency sub-bands at different pyramid levels, and generates the corresponding HDR image from coarser to finer scales. This method can significantly outperform other competitive HDR methods, thereby producing HDR images with high visual quality.

Best Student Paper Award in the 2022 IEEE International Conference on Acoustics, Speech, and Signal Processing

Dr Liang Liu and his collaborators in the Chinese Academy of Sciences won the Best Student Paper Award in the 2022 IEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP) for their paper “Efficiently and Globally Solving Joint Beamforming and Compression Problem in the Cooperative Cellular Network Via Lagrangian Duality". ICASSP is the IEEE Signal Processing Society’s flagship conference on signal processing and its applications. Dr Liu’s research team considers the joint beamforming and quantization problem in the cooperative cellular network, where multiple relay-like base stations connected to the central processor via rate-limited fronthaul links cooperatively serve the users. In this paper, they first show that there is no duality gap between the considered problem and its Lagrangian dual by showing the tightness of the semidefinite relaxation (SDR) of the considered problem. Then they propose an efficient algorithm based on Lagrangian duality for solving the considered problem. The proposed algorithm is highly efficient and is guaranteed to find the global solution of the problem.

Champion of the Tertiary Education Category in the Hong Kong Electronics Project Competition 2022

Supervised by Dr Ivan Ho, our MSc in Electronic and Information Engineering Programme student, Guo Jingtao, obtained the Champion of the Tertiary Education Category in the Hong Kong Electronics Project Competition 2022! The competition was organized by the Electronics Division of The Hong Kong Institution of Engineers (HKIE) with the theme of “Advancing Innovation and Technology in New Normal Smart City” this year. It aims to uplift the awareness and knowledge of Internet of Things (IoT) technologies in Hong Kong, and to nurture engineers to apply innovative IoT technologies to improve the quality of life. The winning project “Channel State Information (CSI) based Self-quarantine Monitoring System” proposed a system to monitor people under self-quarantine using wireless sensing and Artificial Intelligence (AI) technologies. The system is user-friendly and privacy-preserving without the use of any wearable devices. The prize presentation ceremony was held in the Hong Kong Electronics Symposium 2022 on 25 July 2022.

Prof. Gang Li awarded RGC Senior Research Fellow 2022/23

The University has been awarded three of the ten grants under the Research Grants Council's (RGC) Senior Research Fellow Scheme (SRFS) 2022/23. The SRFS aims to provide sustained support to exceptionally outstanding researchers at UGC-funded universities in Hong Kong to facilitate their dedication to research and development. Prof. Gang Li is one of the PolyU outstanding scholars who is conferred the title of RGC Senior Research Fellow and will receive HKD 7.7 million SRFS funding for his research project “Printable Organic Solar Cells: Materials and Device Investigations towards Applications”. Organic solar cell (OSC) is an emerging photovoltaic (PV) technology with distinct advantages in many areas, such as flexible/portable PV, building integrated PV and transparent power applications. Aiming at accelerating the OSC technology, Prof. Li proposed a systematic plan to tackle the challenges in OSC. The project will significantly push forward OSC technology in terms of high efficiency, stability, compatibility with unique applications and being printing friendly. The proposed research represents a new frontier for OSC technology, which integrates chemistry, physics and material science to generate new perspectives in science and come up with solutions to challenging issues in renewable energy.
