Workshop in Biostatistics presents "Machine Learning in Real-world Healthcare Settings: How Far We've Come and Where We Are Going"

Machine Learning in Real-world Healthcare Settings: How Far We've Come and Where We Are Going
Thursday, November 5, 2020 - 2:30pm
Zoom ID 926 9609 8893 (+password)
Prof. Katherine Heller (AI Researcher at Google Medical Brain; Duke University)
Abstract / Description: 

In this talk, I will discuss three real-world Health applications of Machine Learning research, the progress that we have made in deployment to hospitals or directly to individuals, and where we hope to be heading next. In the first part, I will discuss Sepsis Watch, our Sepsis prediction system that has been deployed to the emergency departments of Duke University hospitals. This system performs prediction for incoming patients through a combination of Gaussian Processes, which estimate patient features in continuous time from uneven measurements, and Recurrent Neural Networks. Next I discuss Graph-coupled HMMs, work that we have done making individual-level predictions of disease spread in a social network in influenza, and how this might affect prediction abilities in other diseases, such as Coronavirus. Lastly, I will discuss the iOS app developed to record data on people with Multiple Sclerosis outside of a clinic environment, what collected data and basic analyses imply for our ability to do symptom and subpopulation prediction in this setting, and where we are headed in the future.
