Our PhD students won Track 1 of the Intel Neuromorphic Deep Noise Suppression Challenge

Our PhD students, HAO Xiang and MA Chenxiang, under the supervision of our Assistant Professor, Dr WU Jibin, have triumphed over their global competitors and won the Track 1 (Algorithmic) of the Intel Neuromorphic Deep Noise Suppression Challenge (Intel N-DNS Challenge). The team will receive a prize valued at US$15,000 (approx. HK$117,000) as recognition of their achievement. The Intel N-DNS Challenge aimed to push the boundaries of noise reduction technology by encouraging algorithmic innovation that can lead to higher denoising performance while being efficient when implemented as a brain-inspired neuromorphic system. The Intel N-DNS Challenge consists of two tracks. Track 1 aimed to encourage algorithmic innovation and took place between 16 March to 18 September 2023. Track 2 aims to realise the algorithmic innovation in Track 1 on actual neuromorphic hardware and demonstrate a real-time denoising system, which will take place from Oct 2023 to Mar 2024. The winner was selected based on a holistic evaluation that assessed the audio quality, computational resource usage, solution write-up quality, innovativeness, and commercial relevance of the solutions proposed by the competing teams. HAO and MA’s solution impressed the evaluation committee by demonstrating an audio quality on par with the Intel’s current production-level system, while offering significantly reduced computational cost. The committee also highlighted their achievement of introducing a novel gated spiking neuron model with a learnable and time-varying timescale parameter that experts believe will benefit many different application domains. Additionally, their solution incorporated state-of-the-art techniques from audio denoising, including frequency partitioning, deep filtering, and a loss function to predict DNSMOS using a MetricGAN+ generative adversarial network. Their marvellous work secured them the championship of this challenge.

PolyU Computing Department Tour 2023: Sparked Inspiration among Senior Secondary Students Towards a Bright IT Future

Our department in collaboration with One Lab Incubation Limited and with the support of the Business-School Partnership Programme by the Education Bureau, successfully co-organised two sessions of the “PolyU Computing Department Tour 2023”. The events were held on 3 Nov and 16 Nov, respectively, attracting over 140 senior secondary students and their teachers. The objective of the tour was to provide students with valuable insights into the latest technologies in computing and AI, as well as career development in this field. The event featured expert guest speakers from leading multi-national IT companies. Mr Anthony LEE, Senior Director of the Oracle Technology Service Team, Hong Kong and Taiwan Region, delivered a captivating presentation on how advanced technologies contribute to the success of extreme sports teams. Mr Kenneth WONG, Business Development Team Lead of Google Cloud, shared his view on the impact of generative AI on the education industry. The event also included an IT career talk by Mr Sky TANG, Chairman of CHUNS Group, as well as our departmental outstanding alumnus. Mr TANG shared his experiences and encouraged students to explore entrepreneurship and seize opportunities in the ever-evolving world of technology. As part of the tour, participants also had the chance to explore three laboratories at PolyU, including the HiVE (Hybrid Immersive Virtual Environment Lab), Game Lab and Research Centre on Data Science and Artificial Intelligence. Through participating in the event, secondary school students could learn from industry pioneers and keep abreast of cutting-edge equipment and facilities available in the field, which would spark inspiration and guidance that leads them towards smart future planning.

Dr YANG Lei and his team received the Best Paper Award (Runner-Up) and Graduate Award at ACM MobiCom 2023

The research paper titled "NeRF2: Neural Radio-Frequency Radiance Fields" published by Dr Lei YANG’s team was awarded the Best Paper Award (Runner-up) at the 29th Annual International Conference on Mobile Computing and Networking (ACM MobiCom 2023). The co-authors of the paper are Dr Zhenlin AN, postdoctoral fellow and Ms Qingrui PAN and Mr Xiaopeng ZHAO, our PhD students. The paper proposes a model called Neural Radio-Frequency Radiance Fields (NeRF^2), which is designed to predict the propagation of Radio Frequency (RF) signals in complex environments. The team trained the NeRF^2 model with a few signal measurements to predict the behaviour of a signal at any position when the location of a transmitter is known. The study demonstrated the effectiveness of NeRF^2 in applications such as indoor localisation and 5G MIMO technology. Read the paper: https://dl.acm.org/doi/10.1145/3570361.3592527   Additionally, the team also received a Graduate Award at ACM MobiCom 2023 for a demo developed by Dr YANG, Dr AN, Mr ZHAO and two COMP PhD students, Mr Jingyu TONG and Mr Sicong LIAO. This demo, namely “Radio Frequency Neural Networks for Wireless Sensing”, introduces an innovative architecture called RF Neural Network (RFNN) that emulates the functionalities of a conventional neural network in proximity to or within sensors. Leveraging reconfigurable metasurfaces, RFNN enables high-speed calculations on raw RF signals, offering processing capabilities at the speed of light. The initial findings highlight RFNN's potential in various wireless sensing applications, including material classification, localisation, and gesture recognition, while operating with minimal power consumption. This research holds promise for optimising the sensing capabilities of IoT devices.   ACM MobiCom is a renowned global conference focused on mobile computing and wireless networking. The conference, sponsored by ACM SIGMOBILE, showcases cutting-edge research in areas such as mobile cloud computing, 5G networks, and IoT. It is well-regarded for its rigorous review process and attracts attendees from both academia and industry.

Dr YANG Lei and his team won Best Paper Award at IEEE SECON 2023

Dr YANG Lei, our Associate Professor, along with Dr Zhenlin AN, postdoctoral fellow and Ms Qingrui PAN and Mr Xiaopeng ZHAO, our PhD students,  received Best Paper Award at IEEE SECON 2023.   Their research paper titled "Revisiting Backscatter Frequency Drifts for Fingerprinting RFIDs: A Perspective of Frequency Resolution" was honoured with the Best Paper Award at the 20th Annual IEEE International Conference on Sensing, Communication, and Networking (IEEE SECON 2023).   Researchers have been aware of the potential of utilising the backscatter frequency drift (BFD) as a unique fingerprint for Radio Frequency Identification (RFID) tags for over a decade. By comparing the discrepancy between the actual backscatter frequency and the requested backscatter link frequency (BLF), it is possible to identify the RFID tags at the physical layer. However, the efficacy of this method has been limited due to a low success rate.   Addressing this issue, this paper suggests a new perspective on the low success rate – a low resolution in frequency measurement. In other words, the measurement lacks sufficient ability to effectively distinguish the slight difference in frequency in BFD, resulting in inaccurate results. To overcome this limitation, this paper introduces an innovative solution by significantly augmenting the frequency resolution to enhance the distinctiveness of BFD, thereby the accuracy of identification can be improved, especially when handling a diverse range of RFID tags.   Read the paper: https://web.comp.polyu.edu.hk/csyanglei/data/files/bfdplus-secon23.pdf   IEEE SECON is a distinguished avenue that offers a collaborative space for scholars, industry experts, standards creators, and policymakers to discuss, exchange, and promote ideas and advancements in the realms of sensor, ad hoc, and mesh networks and systems.
