A renowned professor at Hong Kong Polytechnic University (PolyU), and a former artificial intelligence (AI) scientist at Chinese tech giants ByteDance and Alibaba Group Holding, is trying to work with experts across different fields to develop “affordable” domain-specific models.

Yang Hongxia, who joined PolyU’s Department of Computing last year after decades in the technology industry, is at the forefront of an effort to use the capabilities of large language models (LLMs) in specialised applications.
