The cross-validated adaptive epsilon-net estimator

Suppose that we observe a sample of independent and identically distributed realizations of a random variable, and a parameter of interest can be defined as the minimizer, over a suitably defined parameter set, of the expectation of a (loss) function of a candidate parameter value and the random variable...

Keywords: adaption, covering number, cross-validation, loss function, maximum likelihood estimation
