What does this research mean for the field?

A new mathematical framework for neural fields demonstrates that fixed-head attention remains non-Gaussian at infinite channel width and that neural random fields require additional hypotheses for positive-metric quantum reconstruction. Novelty: ClaimNovelty.METHODOLOGICAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Theoretical and computational analysis demonstrates scaling and renormalization constraints in deep neural architectures, highlighting strict limits on quantum field reconstruction.

Key Points

Establish a unified mathematical framework for neural field laws that disentangles width, attention heads, renormalization group coarse-graining, and quantum reconstruction.
Formulated analytical bounds via conditional Gaussian representations, stationary covariance cocycles, Fokker–Planck evolution, and exact decimation on non-Gaussian Gamma families.
Tested 32 fixed attention kernels and conducted supervised experiments on 24 trained models (12 LSTMs and 12 transformers) across three input tasks and three random seeds.
Intermediate-scale training reduced median eight-token Rademacher averaging error from 0.0665 to 0.0256 for LSTMs and from 0.2664 to 0.00493 for transformers.
All 180 sampled scale records satisfied the applicable trajectory-error bound.
Demonstrated that zero one-step training risk fails to guarantee recursive coarse-graining closure, showing neural random fields require separate reflection-positivity hypotheses for positive-metric quantum reconstruction.
