报告摘要: The constrained covariance (COCO) has been proposed for measuring dependence between random vectors. Kernel cross-covariance operators on reproducing kernel Hilbert spaces, as one of kernel methods of COCO which could extract nonlinear dependence, have attracted considerable attention. In this talk we consider learning rates of some estimators associated with kernel cross-covariance. For kernel cross-covariance operators, we bound a weighted summation of estimation errors of empirical singular functions by 16 times of the estimation error of empirical cross-covariance. It is much tighter than the classical result as the latter only bounds each error of singular function individually.
