Abstract
Let (X1,Y1),…,(Xn,Yn) be independent and identically distributed random elements taking values in ℱ×ℋ, where ℱ is a semi-metric space and ℋ is a separable Hilbert space. We investigate the rates of strong (almost sure) convergence of the k-nearest neighbor estimate. We give two convergence results assuming a finite moment condition and exponential tail condition on the noises respectively, with the latter requiring less stringent conditions on k for convergence.
