A September 30, 2026 publication argues that factoring S = WWᵀ changes gradient flow in attention and removes an information-exponent bottleneck that can stall unfactorized models.
On September 30, 2026, a publication about attention argued that factoring the matrix as S = WWᵀ changes gradient flow and removes an information-exponent bottleneck that can stall unfactorized models. The claim concerns how parameterization affects optimization, not merely model dimension or size.
The available summary gives no authors, method, data, or evidence with which to assess the conclusion. To verify it, consult the original publication and check how it defines the bottleneck, which models and conditions it examines, and whether it provides proofs or experimental results.
