arXiv:2606.18524v1 Announce Type: new Abstract: Looped (weight-tied) Transformers apply a shared residual block $N$ times ($h \leftarrow h + \varepsilon\,f(h)$, same $f$ at each step), increasing effective depth without adding parameters. Prior depth-scaling analyses prescribe $\varepsilon = 1/\!\sqrt{L}$ for depth-$L$ residual networks. We show that this is insufficient for looped architectures: weight sharing makes residual updates correlated across iterations, requiring the stronger scaling $\varepsilon = 1/N$. For multi-layer blocks ($L$ unique layers looped $N$ times), we derive a factore
This research provides a foundational theoretical understanding of how to properly scale a specific class of efficient Transformer architectures, which is critical as AI models continue to grow in complexity and resource demands.
Improved theoretical guidance for designing efficient AI models can accelerate advancements in model performance and reduce training costs, impacting the entire AI development ecosystem.
The explicit scaling laws for looped Transformers provide a new blueprint for optimizing these architectures, potentially leading to more stable and transferable models with fewer parameters.
