Designing Rotationally Invariant Neural Networks from PDEs and Variational Methods

no code implementations31 Aug 2021 Tobias Alt, Karl Schrader, Joachim Weickert, Pascal Peter, Matthias Augustin

With only a few small filters, they can achieve the same invariance as existing techniques which require a fine-grained sampling of orientations.

Novel Concepts

Connections between Numerical Algorithms for PDEs and Neural Networks

no code implementations30 Jul 2021 Tobias Alt, Karl Schrader, Matthias Augustin, Pascal Peter, Joachim Weickert

We connect these concepts to residual networks, recurrent neural networks, and U-net architectures.

Sparse Inpainting with Smoothed Particle Hydrodynamics

no code implementations23 Nov 2020 Viktor Daropoulos, Matthias Augustin, Joachim Weickert

Furthermore, we examine the use of Voronoi tessellation for defining the necessary parameters in the SPH method as well as selecting optimally located image samples.
