Law of Neural Interaction: Depth-Width Shape, Interaction Efficiency, and Generalization

arXiv:2605.27989v1 Announce Type: new Abstract: The guidance of scaling laws has increased the resource demands of modern large language models (LLMs), yet it remains questionable whether these models utilize resources effectively under a fixed budget. Previous research has proved superposition as a key contributor to loss. By leveraging the Neural Feature Ansatz, we extend superposition from parameter space to gradient space and define it as neural interaction. We find that under a fixed budget, good generalization is usually accompanied by efficient neural interactions, and the model can be

Why this matters
Why now

The paper provides a theoretical advancement in understanding neural network efficiency, crucial as LLM development pushes resource limits, questioning current scaling law applications.

Why it’s important

A strategic reader should care because this research offers new insights into optimizing AI model generalization and resource utilization, potentially leading to more efficient and powerful AI.

What changes

The focus might shift from simply scaling LLMs based on current scaling laws to also optimizing for 'neural interaction efficiency' to achieve better performance under fixed budgets.
