Quantitative Gaussian-Process limits of Tensor Programs

arXiv:2607.06290v1 Announce Type: new Abstract: We study the infinite-width Gaussian-process limit of random neural networks through the lens of tensor programs, and we provide a quantitative convergence theory in Wasserstein distance. Our main result gives explicit finite-width error bounds, of order inverse square-root of the widths between finite-network executions and their Gaussian-process limits. The framework is architecture-agnostic and covers feed-forward models together with weight-sharing schemes relevant for recurrent and transformer-type architectures.

Why this matters
Why now

The paper provides a quantitative framework for understanding the behavior of random neural networks, an area of active research, offering convergence theory and error bounds for Gaussian-process limits.

Why it’s important

This research provides a deeper theoretical understanding of neural networks, which can lead to more robust, predictable, and potentially more efficient AI model design.

What changes

The explicit finite-width error bounds allow for better quantitative analysis of AI models, shifting from purely empirical observations to theoretically grounded predictions about their behavior.
