Two teams from China have taken out top honours in a leading international artificial intelligence competition.
The teams – both from Huazhong University of Science and Technology (HUST) – were named champions on Thursday of Graph Challenge, a data and graph analysis contest organised by MIT and Amazon.
“Our achievements are the result of collective effort,” said Wang Qinggang, a HUST doctoral student on one of the winning teams.
“We had weekly, sometimes daily, meetings to verify new ideas and revise them based on experimental data.”

Two other Chinese teams – one from the National University of Defence Technology and the other from Huawei Technologies – were the winners in the innovation category.
Launched as an annual competition in 2017, Graph Challenge has attracted entries from a range of academic and corporate players, including software firm Nvidia, Lawrence Livermore National Laboratory and Carnegie Mellon University.
Each year the competition’s organisers challenge entrants to tackle the most challenging problems from industry or the research community, and until last year all of the champions were from the United States.
“We took part in the competition for the first time in 2019 and we noticed all the champions were from US universities or companies. That inspired us to make a breakthrough,” Wang said.
In 2021, an HUST team was named among the champions, with the university going one step further this year to have two in the top ranks.
“[Being named champions] boosted the enthusiasm of the team members, especially the undergraduate students, for research,” Wang said.
Wang was part of the team led by associate professor Zheng Long, from HUST’s school of computer science and technology.


Graph analysis is an emerging area for AI computing and seeks to find links between structures such as a relationship map on social media or transaction histories between a series of accounts.
With high-speed calculations, scientists can track the spread of epidemics such as Covid-19, and police can follow the flow of stolen money between different banks.
The technology could also be applied to traffic navigation and national security, according to industry experts.
China has made progress in AI development in recent years.
But according to Liu Xiaoping, a researcher with the University of Chinese Academy of Sciences, the country still has to catch up.
“China far exceeds the US in total R&D activities, the number of supercomputers, and the application of AI technology,” Liu said.
“But the US retains the global lead in AI development, especially in high-quality R&D activities, attracting researchers, and chip production.”
