Antoine Wehenkel

Postdoctoral Researcher

One important idea is that science is a means whereby learning is achieved, not by mere theoretical speculation on the one hand, nor by the undirected accumulation of practical facts on the other, but rather by a motivated iteration between theory and practice.       Georges EP Box

About me

Since November 2022, I have been a postdoctoral researcher in Machine Learning at Apple under the advisory of Jörn-Henrik Jacobsen (Health AI) and Marco Cuturi (ML Research). I explore strategies to derive robust simulation-based inference algorithms for misspecified simulators and their applications to health technologies. Before joining Apple, I obtained my PhD (FNRS Research Fellowship) in computer science under the supervision of Professor Gilles Louppe (Uliège - Belgium) in October 2022.

During the summer 2021, I interned at Amazon Web Services where I worked on automated code analysis. In 2018, I was graduated in computer engineering (M. Sc.) from ULiège. I spent my last year of study at Ecole Polytechnique Fédérale de Lausanne (EPFL) as an exchange student. There, I did my master's thesis in Jean-Yves Le Boudec's laboratory, which was about the parameters estimation of electrical distribution networks' lines.

In my dreams, I want to boost the interaction between fundamental sciences and machine learning methods with the objective of making scientific discovery but also for building predictive models that can be deployed more reliably in the real world. When I wake up, I try to advance simulation-based inference by exploring new means for implementing more effectively inductive bias into deep generative models. My main research interests are in deep probabilistic modeling, causal models and simulation-based inference.

I am actively looking for permanent research positions both in academia and industry as my post-doctoral contract with Apple expires in November 2023. If you feel your research agenda and mine could be a good match, feel free to reach out to me!

    Readings

    When I find the time, I like reading fiction books. In particular, I often prefer books that treat about Science, Geopolitics and/or History in an accessible way.
    Over the last years my thoughts about Nature have been influenced by two books from José Rodrigues dos Santos: The Einstein Enigma: A Novel and Spinoza - L'homme qui a tué Dieu (I cannot find the english version).
    I also highly recommend these books to anyone seeking for brain entertainment, in decreasing chronological order of reading:
    • Black-out, by Marc Elsberg;
    • Antifragile: Things That Gain From Disorder, by Nassim Nicholas Taleb;
    • La Peste, by Albert Camus.
