Haizhang Zhang, Liang Zhao

摘要:

为了帮助理解应用科学中的各种再生核,我们研究了两个再生核希尔伯特空间的包含关系。建立了相应的再生核的特征映射的特征。给出了广泛使用的平移不变核之间包含关系的完整表。希尔伯特-施密特内核的具体例子。我们还讨论了保存这样的关系下的各种操作的再生核。最后,我们简要地讨论了具有范数等价的特殊包含。

英文摘要:

To help understand various reproducing kernels used in applied sciences, we investigate the inclusion relation of two reproducing kernel Hilbert spaces. Characterizations in terms of feature maps of the corresponding reproducing kernels are established. A full table of inclusion relations among widely-used translation invariant kernels is given. Concrete examples for Hilbert-Schmidt kernels are presented as well. We also discuss the preservation of such a relation under various operations of reproducing kernels. Finally, we briefly discuss the special inclusion with a norm equivalence.
