A chapter in Multiscale, Nonlinear and Adaptive Approximation, 2009, pp 295-324 from Springer

Abstract: Abstract In this paper we investigate the problem of supervised learning. We are interested in universal procedures producing exponential bounds. One main purpose is to link this problem to a general approach on high dimensional linear models in statistics and to propose some tools resulting from a combination of inspirations: many of them coming from previous works of Wolfgang Dahmen and coauthors combined with regression and thresholding techniques. We present different types of algorithms initiated in Wolfgang Dahmen’s (and coauthors) work and provide a new algorithm: the LOL procedure. We prove that it has optimal exponential rate of convergence. We also study the practical behavior of the procedure: our simulation study confirms its very good properties.
