• The 2018 Hong Kong ICT Best Innovation Award for his team's healthcare analytics platform

These accolades not only recognize individual excellence but also reflect positively on HKUST as an institution capable of supporting world-class research. Perhaps more significantly, Professor Guo's influence has transformed the overall research environment at HKUST, fostering greater collaboration between traditionally separate departments and encouraging risk-taking in exploratory research areas. His advocacy for the (AI Strategy) has resulted in the establishment of shared research infrastructure, including the HKUST AI Supercomputing Facility which provides computational resources to researchers across all faculties. This inclusive approach has stimulated innovation in unexpected areas, such as computational humanities and digital heritage preservation, expanding HKUST's research footprint beyond technical disciplines.

Collaboration and Partnerships

Professor Guo has been instrumental in forging strategic collaborations that extend HKUST's research impact beyond academia into industry and public service domains. His approach to partnership emphasizes mutual benefit and knowledge exchange, creating ecosystems where academic research informs practical applications while real-world challenges inspire new research directions. One prominent example is his leadership in establishing the HKUST-WeBank Joint Laboratory on Artificial Intelligence, which focuses on fintech applications including blockchain technology, smart risk management, and regulatory compliance systems. This collaboration has produced several patented technologies and influenced banking practices throughout Greater China. Similarly, his work with the Hospital Authority of Hong Kong has developed predictive analytics tools that help optimize resource allocation and improve patient outcomes across the public healthcare system.

Beyond local partnerships, Professor Guo has cultivated international research networks that position HKUST as a global hub for AI innovation. He serves as the principal investigator for multiple cross-institutional projects funded by the European Union's Horizon Europe program and Hong Kong's Innovation and Technology Commission. These initiatives typically involve consortia of 5-8 institutions from different regions, addressing challenges that require diverse expertise and international perspectives. For instance, the Sino-European Project on Ethical AI Governance brings together researchers from HKUST, Technical University of Munich, University of Oxford, and Tsinghua University to develop frameworks for responsible AI implementation. The benefits of these partnerships extend beyond immediate research outcomes to include:

Future Vision for Data Science and AI

Looking toward the future, Professor Yike Guo envisions a paradigm shift in how we conceptualize and implement artificial intelligence systems. He anticipates that the next decade will witness the emergence of "contextual intelligence" - AI systems that understand and adapt to complex environmental, cultural, and situational factors rather than operating based solely on statistical patterns in data. This evolution, he argues, will require fundamental advances in how machines represent and reason about knowledge, moving beyond current deep learning approaches toward hybrid systems that integrate symbolic reasoning with statistical learning. Professor Guo particularly emphasizes the importance of developing AI that can operate effectively in resource-constrained environments, making advanced capabilities accessible beyond well-funded commercial laboratories and into broader societal applications.

At HKUST, this future vision is already taking shape through strategic initiatives that Professor Guo is helping to lead. The university's ambitious hkust ais 2030 plan outlines several key directions for growth and innovation in data science and AI research:

• Human-Centered AI Systems: Developing AI technologies that augment human capabilities rather than replace them, with particular focus on education, healthcare, and creative domains.
• Sustainable AI: Creating energy-efficient algorithms and computing architectures that reduce the environmental impact of AI systems while maintaining performance.
• Trustworthy AI: Establishing frameworks for transparent, fair, and accountable AI systems that earn public trust through demonstrable reliability and ethical operation.
• Cross-Domain AI Applications: Expanding AI implementation into non-traditional domains including arts, social sciences, and humanities through the hkust interdisciplinary programs.

To support these directions, HKUST is making substantial investments in research infrastructure, including the planned construction of a dedicated AI Innovation Building that will house specialized laboratories, collaborative spaces, and industry partnership facilities. The university is also expanding its academic offerings to include new joint degrees that combine AI expertise with domain knowledge in fields like law, medicine, and public policy. Under Professor Guo's guidance, these initiatives aim to position HKUST at the forefront of the next generation of AI innovation, creating knowledge that benefits both Hong Kong's development as a smart city and global progress in the field. His leadership in establishing the yike guo hkust research legacy ensures that the university will continue to produce groundbreaking work that shapes how artificial intelligence evolves and integrates into society in the coming decades.
