Beyond Neural Collapse: Task-Intrinsic Geometry Governs Neural Representations in Modular Arithmetic
arXiv:2606.08985v1 Announce Type: new Abstract: While neural collapse (NC) predicts that a $K$-class-balanced classifier should organize terminal representations as a $(K-1)$-dimensional simplex equiangular tight frame (ETF), modular addition consistently enters a different regime: networks compress to a two-dimensional cyclic geometry in which both classifier weights and token embeddings lie on circles. We refine the explanation of this phenomenon in three directions. First, we formalize a layerwise non-uniform training mechanism: downstream classifier weights are driven by dense cross-entrop
This research refines our understanding of neural network behavior, especially in specific computational challenges like modular arithmetic, which is crucial as AI systems become more complex and specialized.
Understanding the intrinsic geometry governing neural representations helps in designing more efficient and robust AI architectures and could lead to breakthroughs in specialized AI tasks.
Our previous assumptions about neural collapse and network organization are being challenged, suggesting that task-specific geometries play a more significant role in how AI learns and represents information.
