Local greedy approximation for nonlinear regression and neural network training
Lee Kenneth Jones · The Annals of Statistics · 2000
A criterion for local estimation and approximation in nonlinear regres- sion and neural network training is introduced and motivated. $N$th-order greedy approximation for the regression (or target) function based on the criterion is shown to converge at rate $O(1/N^{1/2})$ in the nonsampling case.
