Abstract:

Cai and Zhang establish two lower bounds for sin Theta distances with spectral and Frobenius norms (Cai, T. T. and Zhang, A., Rate-optimal perturbation bounds for singular subspaces with applications to high-dimensional statistics, The Annals of Statistics, Vol. 46, No. 1 (2018) 60-89). We provide two lower bounds under any unitarily invariant norm. It turns out that our estimation is better in some sense.
