Prof. Qing Li and his research team won the Best Research Paper Award at WI-IAT’20

Congratulations to Prof. Qing Li, Chair Professor of Data Science and Head of COMP, and his research team on receiving the Best Research Paper Award at the 2020 IEEE/WIC/ACM International Joint Conference on Web Intelligence and Intelligent Agent Technology (WI-IAT '20) with the paper titled “EmoChannelAttn: Exploring Emotional Construction Towards Multi-Class Emotion Classification”. The current multi-class emotion classification studies mainly focus on enhancing word-level and sentence-level semantical and sentimental features by exploiting hand-crafted lexicon dictionaries. In comparison, very limited studies attempt to achieve emotion classification task from the emotion-level perspectives, which are to understand how the emotion of a sentence is constructed. Another limitation of existing works is that people assumed that emotion labels are relatively independent, neglecting the possible relations among different types of emotions. In this paper, the team aims at exploring various fine-grained emotions based on domain knowledge to understand the construction details of emotions and the interconnection among emotions. To address the first issue, the team proposes a novel method named EmoChannel to capture the intensity variation of a particular emotion in time series by incorporating domain knowledge and dimensional sentiment lexicons. The resulting information of 151 available fine-grained emotions is utilised to comprise the sentence-level emotion construction. As for the second issue, the EmoChannelAttn Network is introduced to identify the dependency relationship within all emotions via attention mechanism to enhance emotion classification performance. The experiments demonstrate that the proposed method gains significant improvements compared with baseline models on several multi-class datasets. WI-IAT provides a premier forum and features high-quality, original research papers and real-world applications in all theoretical and technology areas that make up the field of Web Intelligence and Intelligent Agent Technology.

Open Education Resources (OERs) Competition – Learn to Learn

To further enhance students’ learning experiences, COMP organised an “Open Education Resources (OERs) Competition – Learn to Learn” from January to June 2020. There are many public domain e-learning materials and OERs such as short videos and websites available online, thus this competition consisted of two parts: Suggesting OERs and Creating OERs, to encourage students to search for and create good OERs. Students first identified a specific learning topic, suggested a good OER from the Internet and provided a learning reflection by indicating what they have learned and why the OER was useful. In phase 2, students created an OER based on their proposed topics. They were required to prepare some learning materials including presentation slides, an animation or a video to explain their topics and then make use of them to educate others as an OER. Shortlisted students were invited to give a presentation in the final assessment. “After the OER competition, I treasure the value of personifying abstract concepts,” said Miss Isabel Madeleine Kemp, the First Prize winner of Creating OER. “An intuitive and metaphorical explanation speaks for itself, intimidating computing concepts would dissolve into understandable knowledge, even in the eyes of a non-expertise.”  “This OER competition encouraged me to take the initiative in learning. I discovered more useful OERs which were helpful for my study and I would like to learn more after joining this contest,” shared Miss Cheuk Lam Leung, the Second Prize winner of Creating OER and Suggesting OER. The competition enabled students to be more responsive to the advancement in computing and its impact. It also provided them with the opportunities to apply the relevant computing tools and software, and successfully instilled their desire and ability to ‘learn to learn’.   Category Student Name Award Suggesting OER (Round 1) ZHANG Caiqi 1st Prize CHOY Hei Man LEUNG Cheuk Lam 2nd Prize SARTAYEVA Yerkezhan SRIVASTAVA Srijan 3rd Prize Suggesting OER (Round 2) MAK Siu Wang 1st Prize ZHANG Caiqi 2nd Prize SARTAYEVA Yerkezhan 3rd Prize Creating OER KEMP Isabel Madeleine 1st Prize Creating OER LEUNG Cheuk Lam 2nd Prize Creating OER CHOY Hei Man 3rd Prize  

COMP alumnus and scholar teamed up to win a Gold Medal at the 2nd Asia Exhibition of Inventions Hong Kong

Congratulations to Dr Abraham Lam, our alumnus and the Founder of MEGA Automation Ltd, and Dr Dan Wang, our Associate Professor, on receiving a Gold Medal in the 2ndAsia Exhibition of Inventions (AEI) Hong Kong with their project “Smart Air-conditioning Platform (SAP) for Optimizing Thermal Comfort & Energy Consumption in Buildings”. Air-conditioning system accounts for more than half of the energy consumption in a building. Thermal comfort is a subjective feeling. Occupants may find an indoor temperature too cold or too warm which is not good for health and productivity and it may lead to energy waste as well. In light of this, Dr Lam has developed an AI algorithm which enables SAP to quantitatively calculate and estimate the thermal comfort of any individuals based on the different environmental and weather conditions like time, outdoor and indoor temperatures, fan speed and ultraviolet index. The platform is also connected to the air-conditioning systems via the Internet of Things (IoT) to support proactive temperature setting mechanisms. It not only increases energy efficiency in a building but also improves the comfort of the indoor environment. Dr Lam obtained his Higher Diploma in Information Systems in 2007, Bachelor of Science (Honours) in Information Technology in 2009 and Doctor of Philosophy in Computing in 2015. During his ten years study at COMP, Dr Lam demonstrated his keen interest in applying cutting-edge technologies to green buildings and smart cities. Before his PhD graduation, Dr Lam won the Entrepreneurship Award of PolyU Micro Fund in 2012 with his outstanding business proposition “Sustainable iBuilding Management Platform”. He later established MEGA Automation Ltd with the support of PolyU startup fund and enhanced the initial model with Dr Wang, the supervisor of his PhD study. Exploiting research outcomes directly in real-world projects is always difficult as there are many unforeseeable factors at the development stage. Throughout the process, Dr Wang provided substantial support on the research side while Dr Lam played a key role in transforming the technology into real-world applications upon receiving the clients’ feedback and the deployment results. The team solved the challenges together and exemplified a close collaboration between academia and enterprise. “I plan to add more features on top of the existing model to further enrich the application scenarios of SAP. I will work with property management and land developers to deploy SAP in the new buildings, hope it becomes part of their smart building solutions,” said Dr Lam. Taking this opportunity, Dr Lam would like to encourage COMP students and alumni to “think big and start from small”. He believes that it is essential to understand a problem and to learn from experience. “There is no shortest path to success, but only by your persistence and patience to get things done.” AEI is the first exhibition cum competition exclusively devoted to inventions from Asia to be hosted in Hong Kong, by partnering with the International Exhibition of Inventions Geneva. Through exhibition and competition under one roof, global experts, inventors in the industry showcase their breakthrough and versatile inventions and solutions to the world. AEI 2019 featured over 35 inventions that competed for the awards including Gold Medal, VC Choice of Award, Geneva Invention Award, IFIA Award and the Grand Award.

Prof. Johan Hoorn won Huibregtsen Prize 2020 with his robotics research project ‘Alice’

We are proud to announce that Prof. Johan Hoorn received the Huibregtsen Prize 2020 at the award ceremony that took place on 5 October 2020 in Haarlem, The Netherlands, with a live stream available to the guests. Prof. Hoorn successfully outcompeted other scholars who perform scientific research on different social concerns, including COVID-19 new treatment options, malaria vaccine, adolescent overweight, and nitrogen threats to nature. He shared the honour with Prof. Elly Konijn of Vrije University Amsterdam for their robotics research project ‘Alice’. Social loneliness is a major problem in an ageing society. Prof. Hoorn and Prof. Konijn have therefore developed ‘Alice’, a robot girl that helps to cope with loneliness among older adults. ‘Alice’ is regarded as an electromechanical grandchild. She relieves loneliness and improves the quality of life by being a companion to older adults, chatting with them and responding empathically. Can robot friendship replace the human counterpart in a social relationship? How will people respond to an artificial object while they know it is not a real human being? What does a robot need to understand others and how to show empathy? Which social role should a robot play to counter loneliness among the elderly? How do we make a robot understand social-emotional language instead of just following instructions? These questions also are investigated in the project ‘Alice’. “As is, Alice’s performance is based on a mix of artificial intelligence and remote-controlled human interference when a conversation goes astray. Currently, we work on language understanding rather than processing,” said Prof. Hoorn. “Over time, we hope such robots can be used for many social challenges in healthcare, education, and services.” The special feature of ‘Alice’ is highly recognised by the jury of the Huibregtsen Prize. In the Jury Report, “The jury unanimously opted for an innovative approach with an impressive result. An integral success story. The particularly passionate approach to a pressing problem. An impressive combination of in-depth, fundamental research and application of knowledge with global impact. Teamwork that outside the scientific comfort zone answers questions and raises others. This scientific and social project is based on an impressive combination of disciplinary expertise and raises deep questions about possible relationships between humans and machines, but also about empathy and moral reasoning. ‘Alice’ is the product of team science, which stimulates the social discussion about social robotics with the use of citizen science and the impact on politics and business. Deep fundamental questions, a highly relevant application, and brilliant science communication.” Prof. Hoorn started his research in the humanities, focusing on fictional characters. After he joined the Department of Computer Sciences of Vrije University Amsterdam, he ventured into avatars and game characters. He later turned to social robots as the universal interface between the digital and the analogue world after implementing several cognitive models in artificial systems. At PolyU, Prof. Hoorn furthers the Robot Brain Server, which handles data, data security, artificial intelligence, and cloud access to make the robot a safe and trustworthy confidante to its user. The Huibregtsen Prize was established in 2005 by the board of the Stichting De Avond van Wetenschap & Maatschappij (The Evening of Science & Society Foundation) in The Netherlands and named after Ir. Wouter Huibregtsen. All public organizations for scientific research in The Netherlands are invited to submit entries. A minimum of four and a maximum of six projects are selected to enter the final stage annually and the prize ultimately goes to a recent groundbreaking research project that combines scientific quality and innovation with clear social relevance.
