2026年10月7日,arXiv Statistics Machine Learning 频道发布一手论文《卫星图像包含多少独立样本?空间依赖数据的泛化界》。论文证明,对于空间相关范围为 r 像素的 n×n 卫星图像,其有效样本量为 Θ(n²/r²),而非通常假设的 n²;作者称该速率是紧致的,不存在算法可获得更优结果。该研究针对空间依赖数据提出泛化界,量化了空间相关性对样本有效性的折减。目前仅见此一篇报道,尚无后续验证或独立评论。

论文证明,对空间相关范围为 $r$ 像素的 $n \times n$ 卫星图像,有效样本量为 $\Theta(n^2/r^2)$ 而非 $n^2$,且该速率紧致、无算法可更优。
