Watson Still Has Much to Learn About Healthcare

July 9, 2015

If you’ve wondered what is taking Watson so long to get its proverbial medical degree, check out IEEE Spectrum’s article, “IBM’s Dr. Watson Will See You… Someday.” When IBM’s AI Watson won Jeopardy in 2011, folks tasked with dragging healthcare into the digital landscape naturally eyed the software as a potential solution, and IBM has been happy to oblige. However, “training” Watson in healthcare documentation is proving an extended process. Reporter Brandon Keim writes:

“Where’s the delay? It’s in our own minds, mostly. IBM’s extraordinary AI has matured in powerful ways, and the appearance that things are going slowly reflects mostly on our own unrealistic expectations of instant disruption in a world of Uber and Airbnb.”

Well that, and the complexities of our healthcare system. Though the version of Watson that beat Jeopardy’s human champion was advanced and powerful, tailoring it to manage medicine calls for a wealth of very specific tweaking. In fact, there are now several versions of “Doctor” Watson being developed in partnership with individual healthcare and research facilities, insurance companies, and healthcare-related software makers. The article continues:

“Watson’s training is an arduous process, bringing together computer scientists and clinicians to assemble a reference database, enter case studies, and ask thousands of questions. When the program makes mistakes, it self-adjusts. This is what’s known as machine learning, although Watson doesn’t learn alone. Researchers also evaluate the answers and manually tweak Watson’s underlying algorithms to generate better output.

“Here there’s a gulf between medicine as something that can be extrapolated in a straightforward manner from textbooks, journal articles, and clinical guidelines, and the much more complicated challenge of also codifying how a good doctor thinks. To some extent those thought processes—weighing evidence, sifting through thousands of potentially important pieces of data and alighting on a few, handling uncertainty, employing the elusive but essential quality of insight—are amenable to machine learning, but much handcrafting is also involved.”

Yes, incorporating human judgement is time-consuming. See the article for more on the challenges Watson faces in the field of healthcare, and for some of the organizations contributing to the task. We still don’t know how much longer it will take for the famous AI (and perhaps others like it) to dominate the healthcare field. When that day arrives, will it have been worth the effort?
