Yet Another Inadequate Placeholder, spun off from statistics.

Two topics of particular interest: estimating conditional densities, and estimating the densities of short subsequences from time series.

Our interest in this paper is in the data-based selection of a variable bandwidth... an automatic selection procedure inspired by the combinatorial tools developed in Devroye and Lugosi... the expected L1 error of the corresponding selected estimate is up to a given constant multiple of the best possible error plus an additive term which tends to zero under mild assumptions"]
