    Depth-Based Classification for Distributions with Nonconvex Support by Daniel Hlubinka, Ondrej Vencalek

    Published 2013-01-01
    “…The data depth approach is used instead of the linear discriminant analysis mostly to avoid the parametric assumptions and to get better classifier for data whose distribution is not elliptically symmetric, for example, skewed data. In our paper, we suggest to use weighted version of halfspace depth rather than the halfspace depth itself in order to obtain lower misclassification rate in the case of “nonconvex” distributions. …”

    Neo-Characterization in the Neo-Victorian Novel by Georges LETISSIER

    Published 2015-12-01
    “…Hopefully, this cursory, panoramic overview might shed some light on the centrality of character (character-building, -skewing, -bending, -sapping and so forth) in operating a shift from Victorian characterization to what may be designated as neo-Victorian neo-characterization; i.e. a renewed return to a familiar novelistic cast. …”
