Small Models, Strong Priors: Architectural Inductive Bias for Parameter-Efficient Neural PDE Solvers
arXiv:2605.25949v1 Announce Type: new Abstract: Neural PDE solvers have followed the scaling trajectory of vision and language, with recent foundation models reaching billions of parameters. We argue that scale is a poor substitute for architectural inductive bias in this domain: structured priors deliver outsized parameter efficiency, and the pattern of where they succeed and fail is itself informative about what they capture. We instantiate this argument in WaveLiT, an architecture combining a discrete wavelet transform for lossless multi-resolution tokenization, an augmented linear attentio
The accelerating trend of large language models hitting computational and energy limits is driving innovation in parameter-efficient architectures.
This development suggests a potential path to far more efficient and capable AI systems, especially in scientific computing, mitigating the reliance on ever-larger models.
The paradigm shifts from brute-force scaling to architectural ingenuity as a primary driver of AI progress in specific domains, making advanced AI more accessible.
