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).

2013 International Conference on Computer and Robot Vision, 2013
-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.

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 ...

SIAM Journal on Scientific Computing, 2011
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 ...

On Bootstrapping Using Smoothed Bootstrap
2019The standard bootstrap method was introduced as a resampling method for statistical inference; it is a computer based method for assigning measures of accuracy to statistical estimates. The bootstrap sample is obtained by randomly sampling n times, with replacement, from the original sample.

Survey bootstrap and bootstrap weights [PDF]
, 2008 In this presentation, I will review the bootstrap for complex surveys with designs featuring stratification, clustering, and unequal probability weights. I will present the Stata module bsweights, which creates the bootstrap weights for designs specified through and supported by svy. I will also provide simple demonstrations highlighting the use of the
