WCPT poster: Introduction to machine learning in healthcare

It’s a bit content-heavy and not as graphic-y as I’d like but c’est la vie.

I’m quite proud of what I think is a novel innovation in poster design; the addition of the tl;dr column before the findings. In other words, if you only have 30 seconds to look at the poster then that’s the bit you want to focus on. Related to this, I’ve also moved the Background, Methods and Conclusion sections to the bottom and made them smaller so as to emphasise the Findings, which are placed first.

My full-size poster on machine learning in healthcare for the 2019 WCPT conference in Geneva.

IBM’s Watson gave unsafe recommendations for treating cancer

In 2012, doctors at Memorial Sloan Kettering Cancer Center partnered with IBM to train Watson to diagnose and treat patients. But according to IBM documents dated from last summer, the supercomputer has frequently given bad advice, like when it suggested a cancer patient with severe bleeding be given a drug that could cause the bleeding to worsen.

I don’t suggest that these findings aren’t problematic, or that isn’t essential for expert systems like Watson to improve in their diagnosis and prediction but I do feel that it’s a bit like blaming a medical student for not being perfect.  Yes, Watson is still learning and won’t always get it right and yes, it can improve. But is it reasonable to hold these systems to standards of performance that we would never expect of human doctors (see the data on the human causes of medical error that lead to patient deaths).

A.I. Versus M.D. What happens when diagnosis is automated?

The word “diagnosis,” he reminded me, comes from the Greek for “knowing apart.” Machine-learning algorithms will only become better at such knowing apart—at partitioning, at distinguishing moles from melanomas. But knowing, in all its dimensions, transcends those task-focussed algorithms. In the realm of medicine, perhaps the ultimate rewards come from knowing together.

This New Yorker article by Siddhartha Mukherjee explores the implications for practice and diagnostic reasoning in a time when software is increasingly implicated in clinical decision-making. While the article is more than a year old (a long time in AI and machine learning research), it still stands up as an excellent, insightful overview of the  state of AI-based systems in the domain of clinical care.  It’s a long read but well worth it.
