English(EN) Approximating Simple ReLU Networks based on Spectral Decomposition of Fisher Information

ReLU 网络分析将 Fisher 信息与球谐函数联系起来

作者 PulseAugur 编辑部 · [1 个来源] · 2026-05-13 04:00

研究人员分析了具有随机隐藏权重的简单两层 ReLU 神经网络的 Fisher 信息矩阵。他们发现特征值分布显著地集中在特定的特征空间上，其中前三个特征空间几乎占了矩阵迹的全部。该研究确定这些主导特征空间对应于二阶或更低阶的球谐函数，并将其与神经切线核的 Mercer 分解联系起来。 AI

影响为简单神经网络的结构提供了理论见解，可能为未来的模型设计和分析提供信息。

基于 Fisher 信息谱分解近似简单 ReLU 网络

arXiv:2505.17907v2 Announce Type: replace Abstract: Properties of Fisher information matrices of 2-layer neural ReLU networks with random hidden weights are studied. For these networks, it is known that the eigenvalue distribution highly concentrates on several eigenspaces approx…
