摘要：

This letter develops an optimal, nonlinear estimator of a deterministic signal in noise, The methods of penalized least-squares and cross-validation (CV) balance the bias-variance tradeoff and lead to a closed form expression for the estimator, The estimator is simultaneously optimal in a ''small-sample,'' predictive sum of squares sense and asymptotically optimal in the mean square sense.
