Felix Petersen

My primary research interest is differentiable relaxations in machine learning. In particular, I'm interested in differentiable logic gate networks for extremely efficient inference, differentiable sorting (networks) for weakly-supervised learning, differentiable rendering, as well as general stochastic gradient estimation and optimization.

Currently, I am a postdoctoral researcher at Stanford University in Stefano Ermon's group.

Previously, I have been working, i.a., at the University of Konstanz, at TAU, DESY, PSI, and CERN.

Research

The focus of my research lies in differentiable relaxations of non-differentiable operations in machine learning. Differentiable relaxations enable a plethora of optimization tasks: from optimizing logic gate networks [1] and optimizing through the 3D rendering pipeline [2, 3, 4] to differentiating sorting and ranking [5, 6] for supervised [7] and self-supervised [8] learning. Beyond differentiable algorithms, this branches out into various domains including stochastic gradient estimation [9], analytical distribution propagation [10], second-order optimization [9, 11], uncertainty quantification [10], fairness [12, 13], and efficient neural architectures [1, 14].
