PolyU J.C.DISI hosts “Northern Metropolis Future Forum Season 2”, advocating for the “Beautiful Northern Metropolis SoInno Action Framework”

Through its “PolyU Northern Metropolis Future Forum” series, The Jockey Club Design Institute for Social Innovation (J.C.DISI) of The Hong Kong Polytechnic University (PolyU) is advocating for a comprehensive five-pathway “Beautiful Northern Metropolis SoInno Action Framework”. Season 2 of the Forum was hosted today with the theme “Where Conservation Meets Prosperity in the Northern Metropolis,” focusing on practical pathways of “Ecological Empowerment” and “Experience Empowerment.” It brought together experts from the Government, academia, industry and local charitable/non-profit organisations to explore how to transform the traditionally perceived dichotomy between conservation and development into a mutually beneficial economic model. Formulating a “Beautiful Northern Metropolis SoInno Action Framework” In his welcoming remarks, Prof. LING Kar-kan, PolyU Interim Vice President (Campus and Facilities) and Director of J.C.DISI, emphasised that the Institute serves as a convergence point for knowledge and practice, and advocates for the “Beautiful Northern Metropolis SoInno Action Framework,” aiming to collaborate with all sectors of society to build a “Beautiful Northern Metropolis.” Through a lens of social innovation, it seeks to advance a vision for the Northern Metropolis that is “people-centred, nature-inspired and harmoniously prosperous”, creating economic value rooted in conservation. Prof. Ling stated, “J.C.DISI hosted the Forum with the aim of creating a cross-sectoral exchange platform. We will continue to gather insights from all stakeholders, draft policy recommendations for submission to relevant departments and actively seek funding to launch pilot projects under the ‘Northern Metropolis SoInno for Good Initiative’. This is not a short-term project; rather, it is a concrete strategic action that implements the latest six-year PolyU Strategic Plan, which aims to propel innovation and impact through sustainable partnerships with the wider community.” Prof. Ling also introduced the concept of the regenerative economy, noting, “This goes beyond merely being an advanced version of sustainable development, also signifying a fundamental revolution in the economic paradigm that redefines the relationship between humans and nature. The development of the Northern Metropolis represents a historic opportunity for Hong Kong to become a global benchmark for regenerative economies. We must move away from outdated notions that oppose development and conservation, and instead foster a new era of economic prosperity grounded in shared value.” Thematic Session 1: Ecological Empowerment – Transforming Fisheries and Agriculture into Multifunctional Industrial Ecosystems Thematic Session 1 featured Mr Patrick LAI, Deputy Director of Agriculture, Fisheries and Conservation of the Government of the Hong Kong Special Administrative Region (HKSAR) of the People’s Republic of China; Prof. James FANG Kar-hei, Associate Professor of the PolyU Department of Food Science and Nutrition; Ms Nicole WONG, Chief Executive Officer of World Wide Fund-Hong Kong; and Mr Jackie LING, Founder and President of the Association of Hong Kong Agricultural Development and Construction. This session explored how to transform the fisheries and agriculture of the Northern Metropolis from single-purpose production into multifaceted industrial ecosystems that encompass ecological, landscape, educational and tourism values. Mr Patrick Lai outlined the policy vision of the “Blueprint for the Sustainable Development of Agriculture and Fisheries.” He emphasised, “Through the pilot projects, including the Long Valley Nature Park and Sam Po Shue Wetland Conservation Park, the Government will deepen partnerships with stakeholders to explore the integration of conservation efforts, and agricultural and fishery activities into new economic frameworks.” Prof. James Fang outlined the development directions of PolyU’s existing marine aquaculture and ecological conservation research, demonstrating how it supports the Government’s policy objectives in advancing modern aquaculture. “Our research team is committed to exploring the relationship between sustainable aquaculture technologies and ecosystem balance. We aim to develop aquaculture models that simultaneously enhance production, improve water quality and support marine biodiversity.” Ms Nicole WONG articulated her view that the true value of wetland ecosystems far surpasses traditional perceptions. They serve not only as natural carbon sinks, flood regulators, biodiversity reservoirs and water purification systems, but should also be viewed as an integrated whole. Through “Nature-based Solutions”, natural capital can be transformed into sustainable momentum for community development. The development of the Northern Metropolis presents an ideal opportunity to establish a new partnership that embodies the principle of “conservation and development as a win-win”, enabling wetland conservation and local innovation to be mutually reinforcing. Mr Jackie Ling shared a vision for transforming the currently abandoned fishponds in the Northern Metropolis into assets with ecological and commercial value. “We can engage businesses to empower fish farmers, creating a streamlined model from production to sales that stabilises demand for fisheries. This approach can generate diverse value from the fishponds, developing ecological tours and attracting tourists with guesthouses and restaurants. Once the fishponds generate commercial value, they can create job opportunities and promote talent training.” Thematic Session 2: The Experience Economy – Redefining Tourism and Nature Interaction Models Thematic Session 2 featured Prof. Stephen TANG, Head of the Countryside Conservation Office of the Environment and Ecology Bureau of the Government of the HKSAR; Prof. Haiyan SONG, Associate Dean of the PolyU School of Hotel and Tourism Management, Director of the Research Centre for Digital Transformation of Tourism and Mr and Mrs Chan Chak Fu Professor in International Tourism; Ms Josephine WOO, Head of the Holistic Education Department of Kadoorie Farm and Botanic Garden; Mr Scott LIM, NbS Project Manager of The Nature Conservancy; and Mr Paul CHAN, Chairman of the Hong Kong Community Heritage Foundation. This session examined how to move beyond “zero-impact” sustainable tourism by rebuilding ecosystems and revitalising cultural heritage through enriching travel experiences. Prof. Stephen Tang shared the Government’s initiatives for promoting rural revitalisation and ecological conservation in remote areas. He highlighted collaborations within the Blue and Green Recreation, Tourism and Conservation Circle with various universities and stakeholders, including a partnership with the PolyU School of Design on the Kuk Po project, as well as other initiatives such as the Lai Chi Wo and Mui Tsz Lam projects. “Through a tripartite collaboration model involving the Government, the community and villagers, we have launched joint projects that resonate with the harmonious coexistence of rural culture and nature.” Prof. Haiyan Song responded to the “Tourism is Everywhere” policy outlined in the Policy Address, discussing how technology can be harnessed to drive regenerative tourism and create a sustainable future for the Northern Metropolis. He emphasised, “Regenerative tourism is not simply about sightseeing, it involves leveraging the natural and cultural resources of the Northern Metropolis to craft unique travel experiences. This approach allows visitors to engage in ecological restoration and cultural heritage preservation processes while generating sustainable income for the local community.” During the case discussion, Ms Josephine Woo shared an innovative experience centred on environmental education and ecological research, “By recognising the importance of habitat diversity and biodiversity conservation, we can sustainably operate various tourism and educational experiences using environmentally friendly methods. For example, our thoughtfully designed activities in regenerative agriculture, deep ecology, art and transformative experiences are all aimed at recovering operational costs, enabling the public to engage in conservation and research in diverse ways.” Mr Scott Lim shared valuable insights from the Pak Nai wetland restoration project, illustrating how nature-based solutions can effectively address climate change, protect biodiversity and create economic opportunities. He emphasised, “Nature is not only something to be preserved, it is also a vital partner in tackling environmental and social challenges.” Mr Paul Chan shared insights from the perspective of deep cultural tourism on how to transform abundant blue-green Northern Metropolis resources and cultural heritage into unique experiential assets. He remarked, “Culture is not a static relic; it is a living tradition.” Through the concept of “Tourism Innovation Studio,” he designed the “Do Good Tour” project to revitalise traditional villages, farmlands and historical sites, thereby fostering sustainable development and providing economic benefits for the community. In her closing remarks, Ms Sam LAM, Deputy Director of J.C.DISI, provided an update on the progress of the seven Northern Metropolis SoInno Actions since the “PolyU Northern Metropolis Future Forum Season 1” in early July. She also announced that Forum Season 3, focusing on “Community Empowerment,” would be hosted early next year. The first three seasons of the “PolyU Northern Metropolis Future Forum” aim to establish the “Beautiful Northern Metropolis SoInno Action Framework” through five empowerment pathways: digital, cultural, ecological, experiential and community. J.C. DISI will continue to harness this framework to unite diverse stakeholders from the Government, industry, academia, research, investment, civil society, culture, youth, science, environment and media, transforming social innovation ideas into concrete pilot projects. The Forum will address topics such as community co-creation, the low-altitude economy, creative tourism in the Northern Metropolis, youth and diverse talent development, intergenerational inclusion and child-friendly cities, leveraging the power of social innovation to create a vibrant and beautiful Northern Metropolis.

The event drew a full house, attracting over 230 PolyU faculty members, students, alumni and members of the public. Two former ambassadors from the Ministry of Foreign Affairs were invited as keynote speakers: Ambassador LUO Linquan, former Director-General of the Protocol Department of the Ministry of Foreign Affairs of the People’s Republic of China, former Ambassador Extraordinary and Plenipotentiary of the People’s Republic of China in the Hellenic Republic and in Ireland, Consul General (Ambassadorial Rank) of the People’s Republic of China in San Francisco, and current Vice President of the China Public Diplomacy Association; and Ambassador SUN Gongyi, former Director-General level Counsellor of the Department of African Affairs of the Ministry of Foreign Affairs of the People’s Republic of China, and former Ambassador Extraordinary and Plenipotentiary of the People’s Republic of China in the Republic of Mauritius.They shared their insights and first-hand diplomatic experiences while exploring the theory and practice of building a “China-Africa Community with a Shared Future”, guiding the audience through the development of China’s foreign policy. Dr LAM Tai-fai, PolyU Council Chairman, remarked, “Through reform and opening-up, China has developed into the world’s second-largest economy. China’s diplomatic endeavours are not only crucial to the Nation’s development but are also closely linked to Hong Kong’s future. With the unique advantage of the ‘One Country, Two Systems’ principle, Hong Kong should leverage its role as a bridge between the Chinse Mainland and the rest of the world, fully embracing its role as a ‘super-connector’ and ‘super value-adder’ to contribute to the Nation’s diplomatic efforts. PolyU is committed to nurturing socially responsible students with a strong sense of national pride and a global perspective, equipping them to drive societal progress and contribute to the Nation’s development. Today’s seminar is a key event of the ‘PolyU Chinese Culture Festival’ and we are grateful to the ambassadors for sharing their experiences, which will deepen our students’ understanding of China’s diplomatic work and strengthen their sense of belonging, recognition and pride.” Ambassador Luo Linquan has held numerous diplomatic posts and possesses extensive experience in foreign affairs. In his keynote speech entitled “Insights into Diplomacy and Foreign Affairs: First-hand Diplomatic Experiences”, he noted that throughout his decades-long career as a diplomat, he had experienced and handled many major diplomatic incidents. During China’s large-scale evacuation of citizens from Libya in 2011, as the then-Chinese ambassador to Greece, with the support of the Greek government, he managed to charter three cruise ships in a few hours, helping 13,000 Chinese citizens evacuate from Libya through Greece and return home. “This was the largest, fastest and most effective overseas protection operation for Chinese citizens since the founding of the People’s Republic of China. We acted swiftly and decisively, embodying the principle of diplomacy for the people, putting people first and valuing life above all,” he said. Another keynote speaker, Ambassador Sun Gongyi, studied at the China Foreign Affairs University and the Graduate Institute of International and Development Studies in Geneva, and has rich experience in African diplomacy. Speaking on “The Theory and Practice of Building a ‘China-Africa Community with a Shared Future’”, he highlighted the importance of launching this initiative. “Amid great changes unseen in a century, marked by strategic competition and multilateral struggles, Africa is a key partner China can rely on. For example, in international organisations and multilateral forums, African countries are often the strongest supporters of China’s proposals and assertions. The significance of the China-Africa Community with a Shared Future extends beyond bilateral relations — it contributes to the creation of a new and fair international order, which holds great importance for the entire world,” he stated. During the Q&A session, the response was enthusiastic. One participant Prof. C. C. CHAN, an Academician of the Chinese Academy of Engineering and Distinguished Chair Professor of the PolyU Department of Electrical and Electronic Engineering, posed questions and shared his insights. He expressed great admiration for the courage of Chinese diplomats in carrying out their duties without fear for their own safety. He also shared that during his visit to Sweden, local officials praised China’s strong diplomacy, which is backed by robust economic and defence capabilities. Ambassador Sun highlighted that the political concept of “Building a Community with a Shared Future for Mankind”, proposed by China’s leadership, has been incorporated into UN General Assembly resolutions, reflecting the country’s wisdom in grasping global trends and the trajectory of human destiny. ***END***

PolyU reshapes AI training paradigm, significantly reducing costs and democratising AI research

The Hong Kong Polytechnic University (PolyU) Academy for Artificial Intelligence (PAAI) has announced achieving several milestones in Generative AI (GenAI) research. The PAAI team is pushing the boundaries of AI with a novel collaborative GenAI paradigm known as Co-GenAI, which has the potential to transform frontier model training from a centralised, monolithic approach into a decentralised one. Significantly lowering training resource requirements, protecting data privacy and removing resource barriers such as graphics processing unit (GPU) monopolies paves the way for a more inclusive and accessible environment for global institutions to participate in AI research. Advances in GenAI research are presently constrained by three major barriers: training foundation models being so computationally prohibitive that only a few organisations can afford it, effectively excluding global academia from frontier model development; domain knowledge and data remaining siloed due to privacy and copyright concerns, particularly for sensitive information in healthcare and finance; and foundation models being static and unable to evolve with emerging knowledge, while retraining each frontier model ab initio consumes an enormous amount of resources and makes rapid iteration impossible. To tackle these challenges, the PAAI team has developed a novel model training framework that enables ultra-low-resource training and decentralised model fusion. The framework is theoretically grounded and has been validated through extensive real-world applications. PolyU is the first academic institution to open-source an end-to-end FP8 low-bit training solution that covers both continual pre-training (CPT) and post-training stages. This approach will set a new standard for training models with FP8 ultra-low resources while maintaining BF16 precision, in turn revolutionising the practice of model training and positioning PolyU among the few institutions worldwide to master this advanced training technique. Compared with BF16, FP8 delivers over 20% faster training, reduces peak memory by over 10% and dramatically lowers training overheads while maintaining performance. The pipeline integrates CPT, supervised fine-tuning (SFT) and reinforcement learning (RL) to achieve BF16 quality while shortening training time and reducing memory footprint. The team has begun exploring even lower-cost FP4 precision training, with initial results reported in academic publications1. In medical applications, the models trained by these pipelines outperform all peer models on diagnosis and reasoning across all key areas2. In research agent application, the models also demonstrate exceptional performance in complex task handling, generalisation and report quality3. Until now, foundation model training has followed scaling laws: more parameters yield broader knowledge and stronger performance. However, centralised training typically requires millions of GPU hours—a resource available to only a few organisations. The PolyU InfiFusion model fusion achieves a key milestone in model fusion research: it uses only hundreds of GPU hours to fuse large models that would otherwise require 1–2 million GPU hours to train from scratch. The team has merged four state-of-the-art models in 160 GPU hours4-5, avoiding million-scale training budgets while delivering fused models that significantly outperform the originals across multiple key benchmarks. The team has published the first theoretical validation of model fusion—a concept championed by Thinking Machines Lab. Through rigorous mathematical derivation, they proposed the “Model Merging Scaling Law,” suggesting there is another viable pathway to artificial general intelligence (AGI)6. Prof. YANG Hongxia, Executive Director of PolyU PAAI, Associate Dean (Global Engagement) of the Faculty of Computer and Mathematical Sciences, and Professor of the Department of Computing, stated, “Ultra-low-resource foundation model training, combined with efficient model fusion, enables academic researchers worldwide to advance GenAI research through collaborative innovation.” The team has also demonstrated the potential of its training pipelines through applications across specific domains, including state-of-the-art medical foundation and cancer AI models that achieve best-in-class performance. With the integration of high-quality domain-specific data, these models can adapt to medical devices for different scenarios, including personalised treatment and AI-based radiotherapy for oncology. In this context, the team is now collaborating with Huashan Hospital affiliated to Fudan University, Sun Yat-sen University Cancer Center, Shandong Cancer Hospital and Queen Elizabeth Hospital in Hong Kong. PAAI has also introduced a leading agentic AI application in deep search and academic paper assistance—a graduate-level academic paper writer with agentic capability that supports a multimodal patent-search engine for end-to-end research and manuscript drafting. Prof. Christopher CHAO, Senior Vice President (Research and Innovation) of PolyU, stated, “AI is a key driver in accelerating the development of new quality productive forces. The newly established PAAI is dedicated to expediting AI integration across key sectors and developing domain-specific models for diverse industries. These initiatives will not only solidify the leading position of PolyU in related fields, but also help position Hong Kong as a global hub for GenAI.” The research project led by Prof. Yang Hongxia is supported and funded by the Theme-based Research Scheme 2025/26 under the Research Grants Council, the Research, Academic and Industry Sectors One-plus Scheme under the Innovation and Technology Commission of the HKSAR Government, and the Artificial Intelligence Subsidy Scheme under Cyberport. It marks a significant step forward for Hong Kong in global AI innovation and accelerating the democratisation and industrial implementation of AI technology.   1InfiR2: A Comprehensive FP8 Training Recipe for Reasoning-Enhanced Language Models,  https://arxiv.org/html/2509.22536v3 2InfiMed: Low-Resource Medical MLLMs with Advancing Understanding and Reasoning, https://arxiv.org/html/2505.23867 3InfiAgent: Self-Evolving Pyramid Agent Framework for Infinite Scenarios, https://arxiv.org/html/2509.22502 4InfiGFusion: Graph-on-Logits Distillation via Efficient Gromov-Wasserstein for Model Fusion, https://arxiv.org/html/2505.13893 5InfiFPO: Implicit Model Fusion via Preference Optimization in Large Language Models, https://arxiv.org/abs/2505.13878 6Model Merging Scaling Laws in Large Language Models, https://arxiv.org/html/2509.24244   ***END***

PolyU research achieves record efficiency in semi-transparent solar cells, advancing the development of building-integrated photovoltaics

Transparent solar cells can be integrated into windows, screens and other surfaces, with immense potential for them to revolutionise the renewable energy sector. However, there are challenges to overcome, one of which is balancing transparency with power conversion efficiency. Semi-transparent organic photovoltaics (ST-OPVs) that offer the dual advantages of efficient energy generation and visually appealing design are thus attracting significant research interest. Researchers at The Hong Kong Polytechnic University (PolyU) have recently developed an innovative parameter to evaluate the potential of photoactive materials for ST-OPVs. By screening for the most promising materials and their combinations, the research has advanced the development of high-performance ST-OPVs and paved the way for their widespread applications in smart windows and sustainable buildings. With their unique discrete absorption, low-cost production and environmental sustainability, ST-OPVs have very significant development potential in the field of building-integrated photovoltaics (BIPV). To fully realise their potential in the BIPV market and beyond, scientists have combined different materials and leveraged advanced device engineering technologies to enhance the efficiency and stability of ST-OPVs, while ensuring that the colour of the product appears natural under sunlight so that the photovoltaic system does not compromise the building’s visual appeal. Prof. LI Gang, Chair Professor of Energy Conversion Technology and Sir Sze-yuen Chung Endowed Professor in Renewable Energy of the PolyU Department of Electrical and Electronic Engineering, together with Research Fellow Dr YU Jiangsheng, introduced a dimensionless parameter, FoMLUE, to screen a series of classic photoactive materials. It takes into account the materials’ average visual transmittance, bandgap and current density by investigating their normalised absorbance. The researchers found that ST-OPVs based on the ternary materials with the highest FoMLUE values demonstrated enhanced thermal insulation and operational stability compared with their counterparts, and achieved record light utilisation efficiency of 6.05% - the highest figure of merit reported for any semi-transparent solar cell. Their research additionally revealed the influence of geographical factors on ST-OPV performance. To explore the power generation and energy-saving performance of ST-OPV glazed windows, the research team developed a transient model to simulate power output and assess its impact on building space cooling and heating loads. The model, applied in 371 cities across China, has shown that over 90% achieved annual load reductions. Geographical analysis has further indicated that regions with hot summers and warm winters are the most suitable for the installation of ST-OPV glazed windows, with the annual total energy saving in these regions reaching up to 1.43 GJ m ⁻². A paper reporting the research, “Semitransparent organic photovoltaics with wide geographical adaptability as sustainable smart windows,” has been published in Nature Communications. Prof. Li said, “As an emerging solar photovoltaic technology, solar windows offer new possibilities for practical deployment in BIPV, renewable energy vehicles and agricultural greenhouses. Our findings highlight the multifunctionality and geographical adaptability of high-performance ST-OPVs in the construction of sustainable and energy-saving smart windows without compromising the integrity of architectural design, showcasing their highly promising commercial prospects.” Moving forward, the research team will continue to enhance the long-term stability of ST-OPVs and scale up development to large-area solar modules, both of which are essential for achieving commercialisation.   ***END***
