Summary: The question of smoothing when using the non-parametric version of the bootstrap for estimation of population functionals is reconsidered. In general, there is no global preference for procedures based on a smoothed version of the empirical distribution rather than the empirical distribution itself.

This paper introduces the notion of ``bootstrap contraction'', a new kind of contraction functions, which the author argues to be more cognitively realistic than most of the other kinds of contractions so far proposed in the literature. Given a belief set \(K\) and a set \(\mathbb{C}\) of operators on \(K\) which take elements of \(\mathcal{I}\) as ...

On the bootstrap and smoothed bootstrap
Communications in Statistics - Theory and Methods, 1989The standard bootstrap and two commonly used types of smoothed bootstrap are investigated. The saddlepoint approximations are used to evaluate the accuracy of the three bootstrap estimates of the density of a sample mean. The optimal choice for the smoothing parameter is obtained when smoothing is useful in reducing the mean squared error.

Des résultats mathématiques nouveaux sur une extension de la méthode du bootstrap proposée par David Mason (1992) sont exposés. L'idée est de pondérer les individus par des poids aléatoires (définis conditionnellement aux observations) imitant les fluctuations de l'échantillonnage (le bootstrap usuel correspondant à des poids multinomiaux).

AbstractChildren use syntax to guide verb learning in a process known as syntactic bootstrapping. Recent work explores how syntactic bootstrapping works—how it begins, and how it interacts with progress in syntax acquisition. We review evidence for three claims about the mechanisms and representations underlying syntactic bootstrapping: (1) Learners ...

Summary: We develop an algebraic multigrid (AMG) setup scheme based on the bootstrap framework for multiscale scientific computation. Our approach uses a weighted least squares definition of interpolation, based on a set of test vectors that are computed by a bootstrap setup cycle and then improved by a multigrid eigensolver and a local residual-based ...

-A new method for initializing Eigenbackground is proposed. The approach does not require supervised or lengthy training, but instead is bootstrapped as a single unobstructed background frame is used to exploit spatial information in place of gathering a temporal history to generate pixel statistics.
