RoVE: Rotary Value Embeddings Attention for Relative Position-dependent Value Pathways

Alejandro García-Castellanos, Maurice Weiler, Erik J Bekkers

Rotary Position Embeddings (RoPE) make attention scores position-relative but leave the value pathway position-blind: the message sent by a value token is the same regardless of it…

Generalized Reduction to the Isotropy for Flexible Equivariant Neural Fields

Alejandro García-Castellanos, Gijs Bellaard, Remco Duits +2

Many geometric learning problems require invariants on heterogeneous product spaces, i.e., products of distinct spaces carrying different group actions, where standard techniques d…

Symmetry-Aware Graph Metanetwork Autoencoders: Model Merging through Parameter Canonicalization

Odysseas Boufalis, Jorge Carrasco-Pollo, Joshua Rosenthal +2

Neural network parameterizations exhibit inherent symmetries that yield multiple equivalent minima within the loss landscape. Scale Graph Metanetworks (ScaleGMNs) explicitly levera…

Equivariant Eikonal Neural Networks: Grid-Free, Scalable Travel-Time Prediction on Homogeneous Spaces

Alejandro García-Castellanos, David R. Wessels, Nicky J. van den Berg +3

We introduce Equivariant Neural Eikonal Solvers, a novel framework that integrates Equivariant Neural Fields (ENFs) with Neural Eikonal Solvers. Our approach employs a single neura…

Learning Symmetries via Weight-Sharing with Doubly Stochastic Tensors

Putri A. van der Linden, Alejandro García-Castellanos, Sharvaree Vadgama +2

Group equivariance has emerged as a valuable inductive bias in deep learning, enhancing generalization, data efficiency, and robustness. Classically, group equivariant methods requ…

Relative Representations: Topological and Geometric Perspectives

Alejandro García-Castellanos, Giovanni Luca Marchetti, Danica Kragic +1

Relative representations are an established approach to zero-shot model stitching, consisting of a non-trainable transformation of the latent space of a deep neural network. Based…
