arXiv:2510.15814v2 Announce Type: replace-cross Abstract: Universality results for equivariant neural networks remain rare. Those that do exist typically hold only in restrictive settings: either they rely on regular or higher-order tensor representations, leading to impractically high-dimensional hidden spaces, or they target specialized architectures, often confined to the invariant setting. This work develops a more general account. For invariant networks, we establish a universality theorem under separation constraints, showing that the addition of a fully connected readout layer secures a
The proliferation of complex data structures and the need for more efficient AI models drive ongoing research into the theoretical underpinnings of neural networks.
Establishing stronger universality theorems for equivariant networks can lead to more robust, data-efficient, and generalizable AI applications across various domains, including robotics and scientific computing.
The theoretical understanding of equivariant neural networks expands beyond restrictive settings, potentially enabling the development of more practical and universally applicable architectures.
