摘要

受机器学习理论中核方法的启发，我们研究了伯恩斯坦算子对再现核希尔伯特空间中函数的均匀逼近。我们根据再现核希尔伯特空间中的函数规范提供了逼近率。此外，还介绍了伯恩斯坦算子收缩特性的案例研究。

Approximating Reproducing Kernel Hilbert Space Functions by Bernstein Operators

Motivated by kernel methods in machine learning theory, we study the uniform approximation of functions from reproducing kernel Hilbert spaces by Bernstein operators. Rates of approximation are provided in terms of the function norm in the reproducing kernel Hilbert space. A case study of contracting properties of the Bernstein operators is also presented.
