Inspiration Exchange is a series of engagement sessions aiming to share ideas and discuss topics that will define the future of machine learning in healthcare. These events will target machine learning researchers interested in healthcare, and will emphasize sharing of new ideas and development of new methods, approaches, and techniques.
As a lab, our purpose is to create new and powerful machine learning techniques and methods that can revolutionize healthcare. This doesn’t happen in a vacuum. At inception, we are inspired by ideas and discussions; in implementation, we need connections, trust, and partnership to make a real difference.
While you can learn about our work at major conferences in machine learning or in our papers, we think it’s a better idea to create a community and keep these conversations going. We’re also aware that many people—both in healthcare and machine learning—have questions about what we do, and how they can contribute.
For more information about Inspiration Exchange—and to sign up to join in—please have a look at the sections below, and keep checking for new updates.

Session 25: Causal Deep Learning
In this session, Prof. Mihaela van der Schaar and Ph.D. student Jeroen Berrevoets unveiled our lab’s latest causal deep learning (CDL) manifesto (paper and slides attached). Please find below an abstract of our vision for the future of CDL:
Causality has the potential to truly transform the way we solve a large number of real-world problems. Yet, so far, its potential remains largely unlocked since most work so far requires strict assumptions which do not hold true in practice. To address this challenge and make progress in solving real-world problems, we propose a new way of thinking about causality – we call this causal deep learning. The framework which we propose for causal deep learning spans three dimensions: (1) a structural dimension, which allows incomplete causal knowledge rather than assuming either full or no causal knowledge; (2) a parametric dimension, which encompasses parametric forms which are typically ignored; and finally, (3) a temporal dimension, which explicitly allows for situations which capture exposure times or temporal structure. Together, these dimensions allow us to make progress on a variety of real-world problems by leveraging (sometimes incomplete) causal knowledge and/or combining diverse causal deep learning methods. This new framework also enables researchers to compare systematically across existing works as well as identify promising research areas which can lead to real-world impact.
The session also featured a lively roundtable discussion with our panel of experts Dr. Cheng Zhang (Microsoft), Dr. Guillermo Sapiro (Apple, Duke), and Dr. Simon Woodhead (Eedi), who shared their insights on the applications and developments of causal deep learning.

We encourage everyone to engage with this agenda, and together build the future of CDL!
