Anthony Ledford and his colleagues at Man AHL spent three painstaking years building a machine-learning model to do something mere mortals often can’t: find fresh ideas in an avalanche of data.

To Ledford, a lot of the buzz smacks of hype. The technology is more robust than its predecessors but hardly revolutionary.
