The Hong Kong Polytechnic University (PolyU) and Alibaba Cloud, the cloud computing arm of Alibaba Group, signed a Memorandum of Understanding (MoU) today to strengthen their cooperation in Artificial Intelligence (AI) research, particularly focusing on the areas of smart cities and smart healthcare. The two parties hope to translate research findings into real applications which can be initially adopted in Hong Kong as a pilot and then rolled out to the rest of the Greater Bay Area and other overseas cities.
