HÀ NỘI — Competing with 2,200 artificial intelligence (AI) experts worldwide, Nguyễn Hồng Đăng, an expert of Viettel Cyberspace Centre - a member of Viettel Group, won first prize at the contest "Detecting breast cancer through mammography screening".

The competition is organised and launched by the Radiological Society of North America (RNSA) on the Kaggle platform, with the participation of the world's largest community of AI and data science professionals.

According to the jury's assessment, Đăng's solution has solved the data imbalance in AI model training.

In the data file provided by the contest, the proportion of labelled malignant cancer samples accounted for only about 2 per cent of the total number of samples. In comparison, the samples labelled as benign or normal accounted for 98 per cent. Imbalanced Data can cause artificial intelligence to make false predictions.

“We are completing the solution into a service on the Viettel AI Platform. Hospitals, medical organisations and individuals can easily access and use them for work. This solution will save time and cost compared to Self-Studying Machine Learning,” said Nguyễn Mạnh Quý, Director of Viettel Cyberspace Centre. — VNS
