IBM’s Watson enters medicine

IBM’s first TV commercial advertising Watson’s capabilities in medicine. I find this system incredibly fascinating. Medicine has evolved to the point where it is no longer possible to know every aspect of every disease. Watson promises to help doctors improve diagnosis and better tailor treatments to individual patients.

Watson’s technical specifications:

  • 90 IBM Power 750 servers enclosed in 10 racks
  • 16 Terabytes of memory
  • A 2,880 processor core
  • Linux system
  • While not officially disclosed by IBM, Watson is estimated to have cost $1-$2 billion
  • Uses “DeepQA”: a technology that enables computer systems to directly and precisely answer natural language questions over an open and broad range of knowledge
