新研究表明,结构化特征在机器学习模型中会过拟合

研究人员已证明,在参数过多的岭回归中,结构化特征图会导致过拟合,而无结构的随机特征图则能泛化。具体而言,在 $\mathbb{Z}_p^2$ 上的限带傅里叶特征图,即使在插值阈值以下,随着频带的增加,其准确性也会下降。研究发现,活跃模式的数量,而非容量比,对性能有显著影响,这凸显了特征几何在泛化中的重要性。 AI

影响 强调了特征几何在模型泛化中的关键作用,可能指导未来的模型设计。

    结构化特征过拟合,随机特征则能理解

    arXiv:2609.15047v1 Announce Type: new Abstract: Xu, Vardi and Safran (ICML 2026) prove that over-parameterized ridge regression over an unstructured random Gaussian feature map groks, with the delay between memorization and generalization growing as $1/\lambda$ in the weight deca…
