Algebraic Topological Networks via the Persistent Local Homology Sheaf

no code implementations16 Nov 2023 Gabriele Cesa, Arash Behboodi

The intermediate features of our networks live in these vector spaces and we leverage the associated sheaf Laplacian to construct more complex linear messages between them.

Neural Lattice Reduction: A Self-Supervised Geometric Deep Learning Approach

no code implementations14 Nov 2023 Giovanni Luca Marchetti, Gabriele Cesa, Kumar Pratik, Arash Behboodi

Lattice reduction is a combinatorial optimization problem aimed at finding the most orthogonal basis in a given lattice.

Implicit Convolutional Kernels for Steerable CNNs

1 code implementation NeurIPS 2023 Maksim Zhdanov, Nico Hoffmann, Gabriele Cesa

Steerable convolutional neural networks (CNNs) provide a general framework for building neural networks equivariant to translations and transformations of an origin-preserving group $G$, such as reflections and rotations.

A PAC-Bayesian Generalization Bound for Equivariant Networks

no code implementations24 Oct 2022 Arash Behboodi, Gabriele Cesa, Taco Cohen

Equivariant networks capture the inductive bias about the symmetry of the learning task by building those symmetries into the model.

A Program to Build E(N)-Equivariant Steerable CNNs

no code implementations ICLR 2022 Gabriele Cesa, Leon Lang, Maurice Weiler

This enables us to directly parameterize filters in terms of a band-limited basis on the base space, but also to easily implement steerable CNNs equivariant to a large number of groups.

A Data and Compute Efficient Design for Limited-Resources Deep Learning

no code implementations21 Apr 2020 Mirgahney Mohamed, Gabriele Cesa, Taco S. Cohen, Max Welling

Thanks to their improved data efficiency, equivariant neural networks have gained increased interest in the deep learning community.
