Sampling discretization and related problems

B. Kashin, E. Kosov, I. Limonova, V. Temlyakov

摘要:

本调查解决抽样离散化及其与其他数学领域的联系。综述集中于有限维子空间元素范数的抽样离散化。在这里,我们提出了已知的结果采样离散化的整体规范和统一的规范开始与经典的结果和最近的成就结束。我们还展示了采样离散化如何连接到子矩阵的谱性质和算子范数,有限维子空间的嵌入,高维分布的边缘矩和学习理论。随着相应的结果,证明这些结果的重要技术进行了讨论。

英文摘要:

This survey addresses sampling discretization and its connections with other areas of mathematics. The survey concentrates on sampling discretization of norms of elements of finite-dimensional subspaces. We present here known results on sampling discretization of both integral norms and the uniform norm beginning with classical results and ending with very recent achievements. We also show how sampling discretization connects to spectral properties and operator norms of submatrices, embedding of finite-dimensional subspaces, moments of marginals of high-dimensional distributions, and learning theory. Along with the corresponding results, important techniques for proving those results are discussed as well.
