  author={Chao Ying and Zhou Yu},
  journal={arXiv: Statistics Theory},
We in this paper consider Frechet sufficient dimension reduction with responses being complex random objects in a metric space and high dimension Euclidean predictors. We propose a novel approach called weighted inverse regression ensemble method for linear Frechet sufficient dimension reduction. The method is further generalized as a new operator defined on reproducing kernel Hilbert spaces for nonlinear Frechet sufficient dimension reduction. We provide theoretical guarantees for the new… Expand

Kernel Methods for Measuring Independence
Two new functionals, the constrained covariance and the kernel mutual information, are introduced to measure the degree of independence of random variables and it is proved that when the RKHSs are universal, both functionals are zero if and only if the random variables are pairwise independent.
