|The Old Watson|
WATSON, an IBM supercomputer, spectacularly beat its human rivals in a 2011 edition of “Jeopardy!”, an American quiz show. It has got smarter since then. Its components have shrunk from room-size to briefcase-size; its processing speed has more than tripled. The sleeker, faster Watson is now being put to commercial use: its first application is suggesting treatments in cancer clinics.Supporting medical diagnosis is a great application for artificial intelligence. If we can tie in the huge date bases that will be developed with online patient record systems we may really be able to improve diagnosis.
