PolyU Library Virtual Reality Contest 2020

We are glad to announce that two of our undergraduate students, Declan Leung Chun-hin, (BSc (Hons) in Enterprise Information Systems, Year 4) and Wu Chun-hung, (BSc (Hons) in Computing, Year 3) have recently won the Champion and First Runner-up with their projects titled “Chernobyl Disaster” and “Green Ark” respectively in the Virtual Reality (VR) Contest organised by the PolyU Library. Declan teamed up with another student from the Department of Health Technology and Informatics (HTI) to create their VR work “Chernobyl Disaster”. It was a storytelling simulation of the Chernobyl nuclear catastrophe. Users could immerse themselves in conducting a VR safe test on a nuclear reactor and get the first-person experience in the incident. “Green Ark” was based on PolyU’s Green Deck plan to build a green public park above the Hung Hom Cross-Harbour Tunnel for recreation use. Chun-hung added a VR effect to let people connecting with this green space. “I have been engaged in VR and game development for at least four years. Joining this contest allowed me to re-examine my weaknesses and ability to complete a single game,” Chun-hung shared. To prepare and encourage students to participate in the contest, a series of online workshops and webinars related to VR was held from October 2020 to April 2021 for them to pick up skills that help them develop their own VR application.

Inauguration Ceremony for PolyU Student Ambassadors 2021-22

Under the “PolyU Student Ambassador Scheme”, vibrant students are appointed as Student Ambassadors (SAs) to promote PolyU to secondary students and the general public through outreaching activities such as Info Day, admission talks, etc. This year, we are glad to announce that two energetic and enthusiastic COMP students are being appointed as PolyU SAs and the Inauguration Ceremony was held on 10 September 2021. Prof. Wong Kwok-yin, Vice President (Education) of PolyU delivered the welcome speech and presented the Certificate of Appreciation to SAs of the previous year in recognition of their contributions, followed by the presentation of the official appointment to new SAs by Mr Edward Shen, Registrar of PolyU. Our student, Declan Leung Chun-hin (BSc (Hons) in Enterprise Information Systems, Year 4) was invited to give a delightful sharing on why he joined the scheme and his expectations. Another student, Isabel Madeleine Kemp, (BSc (Hons) in Computing, Year 4) also shared with us how grateful she was being one of the ambassadors. “When I was still a secondary student, I remembered being perplexed and overwhelmed by selecting my major, wondering where my passion lay and what my dreams were. Just by reading information from the Internet, isn’t enough for the younger generation to grasp and understand what the discipline is,” Isabel said. “I want to take my sharing opportunity, to give secondary students my perspective on studying at PolyU and Computing.” The scheme has been running by the Academic Registry consecutively for 20 years since 2001. To provide SAs with a better understanding of the strength of PolyU and the University’s admission arrangements as well as to further improve their communication and leadership skills, a series of training and briefings were offered to them. They will share their first-hand experience with prospective applicants and actively participate in various promotional activities. In return, they can strengthen their sense of belonging towards the University as well as enhance their communication, leadership presentation, and social skills. We sincerely hope that our SAs will be well equipped to perform their ambassadorial duties for the Department, Faculty and the University in the upcoming year.

Dr Jieming Shi received the Best Paper Award at VLDB 2021

We are pleased to announce that Dr Jieming Shi, Assistant Professor of COMP, together with other five researchers from Nanyang Technological University, National University of Singapore and Hamad Bin Khalifa University received the Best Paper Award at the 47th International Conference on Very Large Data Bases (VLDB) held from 16 – 20 August 2021 with the paper titled “Scaling Attributed Network Embedding to Massive Graphs”. Given a graph where each node is with a set of attributes, attributed network embedding (ANE) maps each node to a compact vector, which can be used in downstream machine learning tasks. Ideally, the vector should capture the node's affinity to each attribute, which considers not only the node's own attributes but also those of its connected nodes in the graph. It is challenging to obtain high-utility embeddings; scaling effective ANE computation to massive graphs pushes the difficulty of the problem to a whole new level. In this paper, Dr Shi and his team presented “PANE”, an effective and scalable ANE approach for massive graphs, which achieves state-of-the-art quality, measured by the accuracy of three prediction tasks. In particular, for a large graph with over 59 million nodes, 0.98 billion edges, and 2000 attributes, “PANE” is the only known viable solution that obtains effective embeddings on a single server, within 12 hours. “PANE” obtains superior performance through three main algorithmic designs. First, it formulates the learning objective based on a novel random walk model. Second, “PANE” includes an efficient solver for the objective, to drastically reduce the training cost. Finally, “PANE” utilizes multi-core CPUs through non-trivial parallelization, which achieves scalability while retaining the high quality of the results. VLDB is a premier annual international forum for data management and database researchers, vendors, practitioners, application developers, and users. The VLDB 2021 conference featured research talks, tutorials, demonstrations, and workshops. It covered issues in data management, database and information systems research.
