Practical Benefits & SOTA
Our theoretical work proves that for approximately equivariant encoders, the latent space almost surely contains the regular representation. This fundamental algebraic insight guides our novel approach.

Persistence Despite Invariance Pressure
Our research revealed a critical insight: despite training for invariance, linear probes show that the regular representation persists in a decodable state. This suggests a nuanced process where AI models achieve desired outcomes through geometric contraction rather than outright information erasure.
Challenge: Maintaining informative latent space under invariance constraints.
Solution: Leveraging the inherent algebraic structure.
Outcome: Robust feature preservation, 60.6% accuracy in recovering input rotation from invariant features.
We empirically validate our theory across various tasks, observing that neural networks naturally learn representations aligned with the regular representation, even for non-analytic activations.
| Group | Model | Irrep. Counts (-1,+1/Triv,Sgn,Std) | Alg. Loss | Eq. Loss |
|---|---|---|---|---|
| C2 | Analytic AE | 3:5 | 9.9e-10 | 1.6e-3 |
| D3 | Analytic AE | 3:3:5:9 | 1.1e-4 | 1.4e-2 |
| C4 | Analytic Classifier | 4:4:4:4 | 1.5e-4 | 1.8e-3 |
Notes: Networks consistently learn a high-fidelity multiple of the regular representation, with each independent data orbit contributing one copy.
ReLU Compatibility
Non-analytic (ReLU-based) encoders exhibit identical behavior, converging to regular representation copies.
By directly imposing the regular representation as an inductive bias, our parameter-free method achieves competitive or superior performance to complex, specialized models across diverse tasks.
