On April 8, contest organizers will reveal all but the top 10 place holders, and those 10 will be informed privately. During the following eight weeks, their algorithms will be verified.
The winning entry and its $3 million prize—or its $500,000 one, will be announced at Health Datapalooza IV June 3 or 4 in Washington, DC.
