The NUS-NUHS-MIT Healthcare AI Datathon and EXPO is a focal point to showcase and discuss the application of Articial Intelligence (AI) in clinical practice and its implications in the age of precision medicine. We shall be hosting a number of healthcare AI workshops during this event, to introduce participants to the skills required for building AI tools. In particular, NUHS shall be demonstrating the capabilities of the DISCOVERY AI platform, a production level, secure sandbox for building AI tools from large multi-domain medical databases. This platform shall be the basis for the Datathon held on the 7th to 8th July at the Saw Swee Hock School of Public Health at NUS. Concurrently, we shall be hosting companies demonstrating their technical capabilities in the healthcare field at the healthcare EXPO from 3rd to 6th July.
