本文讨论流形估计的极小极大收敛率。通过两组流形的新颖构造和 Le Cam (1973) 凸包测试方法的应用,获得了新的下界。极小极大下限与上限匹配至一个常数因子。 MSC 2010 学科分类:初级 62C25、62G86;次级 65C50。
This paper deals with minimax rates of convergence for mani- fold estimation. A new lower bound is obtained by a novel construction of two sets of manifolds and an application of convex hull testing method of Le Cam (1973). The minimax lower bound matches the upper bound up to a constant factor. MSC 2010 subject classications: Primary 62C25, 62G86; secondary 65C50.
