About

I'm Finn Sherry. I'm a PhD candidate in Remco Duits' Geometric Learning & Differential Geometry group at TU/e.

Picture of me I am a part of the EAISI-funded research project "New Memory Efficient Geometric Learning for Automatic Crack Detection in Bridges". Our goal is to develop and improve Geometric Deep Learning (GDL) techniques. Current GDL algorithms, such as Group-equivariant Convolutional Neural Networks (G-CNNs), have a proven track record in low data applications, but often struggle when dealing with many large images. We are investigating various ways to make scaleable GDL algorithms, e.g. by reducing their memory footprint. In the end, we hope to apply our new techniques to automate the detection of cracks in infrastructure: the vast quantity of high resolution images in this application makes current GDL methods impractical.

In addition to machine learning and (differential) geometry, I like analysis, PDE theory, and mathematical physics. I am also interested in history, particularly classical antiquity, and I'm a member of the Dutch classics association NKV.

I am on a REMODEL exchange visiting Erik Jansson at the Cambridge Image Analysis group. I gave a presentation during the group meeting; here are my slides.

I created a visualisation for the Lie group of similarity transformations and its exponential.


Diffusion-Shock PDEs for Deep Learning on Position-Orientation Space has now been published in the JMIV special issue for SSVM 2025!

I presented Flow Matching on Lie Groups at GSI 2025. I made some changes after my presentation at the 4th AIM cluster event; these are my new slides.

I presented my paper Orientation Scores should be a Piece of Cake at GSI 2025. The slides I used are available here.

I helped organise the 4th AIM PhD Networking Event, and gave a tutorial on equivariance. You can find the tutorial on my GitHub.

We were invited to extend Diffusion-Shock Filtering on the Space of Positions and Orientations for the JMIV special issue on SSVM (2025). The preprint of our extension Diffusion-Shock PDEs for Deep Learning on Position-Orientation Space is now on arXiv.

I created a brief explainer of the iterative eikonal PDE scheme that we used in Crossing-Preserving Geodesic Tracking Spherical Images. I also wrote a shader on Shadertoy showing the method in practice.


I presented Flow Matching on Lie groups at the 4th AIM cluster event in Tilburg. Here are the slides.

My paper Diffusion-Shock Filtering on the Space of Positions and Orientations won the Best Student Paper Award at SSVM 2025! These are the slides I used for my oral presentation. SSVM 2025 Best Student Paper Award
