Huber损失函数集的V_γ维
ON THE V_γ DIMENSION OF THE SET OF HUBER LOSS FUNCTION
【摘要】 研究了无限再生核希尔伯特空间 (RKHS)中半径为R的球内回归估计的Huber损失函数集Vγ 维的有限性 ,给出其Vγ 维的上界估计 ,从而保证此类回归机器的依概率一致收敛 ,使其具有较好的推广能力
【Abstract】 Finiteness of the V γ dimension of the set of Huber loss function for regression is studied in a ball of radius R in an infinite dimension RKHS,and an upper bound of it is estimated. Therefore it provides the uniform convergence in probability for this kind of regression machine and guarantees regression machine having better generalization performance.
