University of Cambridge (Girton College) Online Summer Programme - Mathematics for Engineering

Co-organised by Girton College of the University of Cambridge and the Faculty of Engineering (FENG) of PolyU, the “University of Cambridge (Girton College) Online Summer Engineering School” was held from 26 – 30 July 2021. Thirty-nine FENG students including nine from COMP joined the programme. Dr John Longley, Senior Lecturer of the Department of Engineering from the University of Cambridge, delivered a course “Mathematics for Engineering”. Focusing on the theoretical concept, the course covered useful knowledge for engineers, including vectors analysis, matrices algebra, numerical solutions and quadrature, statistics, as well as data analysis. Daily homework assignments were given to participants after each class. “I chose to join this programme to enhance my mathematic ability and skills,” Liu Yunfei (BSc (Hons) in Computing, Year 2) said. “I learnt essential knowledge about some basic mathematic methods and techniques, which can be easily applied to my major study.” To enable participants to know more about Girton College and Cambridge student life, a series of special events were arranged such as Orientation, Watch Party of Girton College Experience, Guest Lecture on Graduate Studies at Cambridge. Students were also honoured to meet with the Mistress of Girton College, Prof. Susan Smith on 29 July, discussing education-related topics. Apart from the class learning, the summer programme also offered attendees opportunities to communicate with students who are currently studying at Girton College. Social activities with Student Ambassadors like “Quiz and Discussion Night” and “Walking Tour of Girton College”, further allowed students to experience the Cambridge study life. “Every day there was one challenge question at the end of the lecture for us to practice what we have learnt. I found this was so encouraging and interesting by solving the problem,” Geng Longling (BSc (Hons) in Computing, Year 2) shared. In conclusion, the programme provided students with valuable international learning experience in various aspects. “At Girton College we are very fortunate to have collaborated on short-term programmes with PolyU over a number of years now. The PolyU students on this new Mathematics for Engineering programme were as hard-working as always, and it is wonderful to know that even though the programme was delivered online the students still learnt a lot academically, and even got to experience something of Girton College life through the additional activities that were organised. We look forward to welcoming further PolyU students to Cambridge in future.” Dr Nick Godfrey, Director of Summer Programmes said.

UG Summer Research Experience at MIT Hong Kong Innovation Node

Sponsored by PolyU’s UG Summer Research Abroad Sponsorship Scheme (USRA), six COMP students participated in a 6-week summer research programme at the MIT Hong Kong Innovation Node from 15 June to 30 July 2021. USRA is a signature student learning scheme, which aims to provide financial support to encourage students to undertake research under the guidance and supervision of academics in overseas pre-eminent universities. The core part of this summer research programme was to first identify a real-world problem related to “Smart City” and proposed solutions. Geng Longling and Liu Yunfei (BSc (Hons) in Computing, Year 2) teamed up with Lam Long-ting (BSc (Hons) in Computing, Year 3) as well as a secondary school student to work on a “Smart Traffic Light System”. Smart traffic lights are one of many smart city initiatives that use advanced technology to improve the management of city services and the quality of life for citizens. The traffic lights are based on a dynamic algorithm that can control the lights based on the population and vehicles density. “By working with MIT people, I have a chance to exchange ideas with the most intelligent brains in the world. I was inspired by their awesome ideas and I realised that I need to reconsider my previous ways of thinking,” Yunfei said. Cao Qun, Xu Ying (BSc (Hons) in Computing, Year 3) and Muhammad Shoaib (BSc (Hons) in Enterprise Information Systems, Year 4) worked on other three projects and one of them was “The Supermarket Navigation System”. With the indoor navigation algorithm, customers can search the products they would like to purchase and the system will send the optimal path to the customers so that they can locate the products in the supermarket easily and efficiently. “The experience at the MIT Hong Kong Innovation Node was extremely enriching,” Muhammad shared. “I have learned a lot about IoT and Android app development.” By the end of the programme, students had to give presentations at the Hong Kong Science and Technology Parks (HKSTP) in front of a panel of IoT experts who gave valuable comments and professional advice. During this research internship, participants could gain not only technical knowledge but also teamwork and soft skills.

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.
