Watson robots are becoming the world's top medical experts

Before speaking at the WIRED Health Conference, Kyu Rhee, IBM's Chief Health Officer, took out an iconic medical device from his pocket: a stethoscope.

The first stethoscope born in the world was a mono stethoscope, invented by French doctor René La ennec1781--1826, which has been around for 200 years. During these two hundred years, no matter how advanced the technology is, there are various non-invasive techniques for internal examination of the body, but the stethoscope is always the medical device that best represents the "doctor". A 2012 study showed that doctors carrying stethoscopes are more professional and more worthy of patient trust.

"Amazingly, until today, medicine still uses stethoscopes in certain areas," Rhee said. "But I believe that in the next 200 years, cognitive robots like Watson will replace stethoscopes and become future medical care. a part of."

IBM's Watson robots produce results based on cognitive computing to absorb both structured and unstructured data. To master a discipline, Watson first has to absorb a large amount of existing data, and then the experts will enter the established questions and answers to train them. Watson will then be asked a question that does not give an established answer. Watson uses his own understanding of the problem to list thousands of possible answers and to sort the answers. The more Watson answers, the better it understands.

New vision for cancer treatment

Stethoscopes have existed for two centuries, and during this time, medicine has undergone earth-shaking changes. Jose Balsega, chief physician of the Memorial Sloan Kettering, lists the rapid changes in cancer treatment since the Watson robot. In response to these changes, thousands of articles appear every year in the medical field. New imaging technologies such as PET scanning, CAT scanning and ultrasound imaging have brought new hopes for cancer treatment. At the same time, the rise of genomics has made cancer cell sequencing and patient genetic analysis possible. In the 1960s, doctors had only two diagnostic options for a particular disease, but today's doctors may have 50 different treatments that are recommended and not recommended.

Commemorating Memorial Sloan Kettering

Watson wants to help doctors treat diseases. It's not that simple. From the beginning, you have to start from "reading" honestly. First, Watson must first read all accessible medical literature. At the same time, it also reads the clinical records of the Memorial Sloan-Kettering Hospital and the reasons for the doctor's treatment plan. For Watson, it can read millions of words in seconds. At the same time, it also understands the natural language, including the use of medical records and journal articles, even the doctors themselves look at the complex language. Not only that, Watson is not just a nerd who can only "read". It can apply all the knowledge he has learned to new cases and advise doctors based on all the medical knowledge he knows.
