On a class of smoothed Good–Turing estimators Su una classe di stimatori di Good–Turing lisciati

Under the assumption of a two parameter Poisson-Dirichlet prior, we show that Bayesian nonparametric estimators of discovery probabilities are asymptotically equivalent, for a large sample size, to suitably smoothed Good–Turing estimators. A numerical illustration is presented to compare the performance between Bayesian nonparametric estimators with corresponding smoothed Good–Turing estimators...

Una piattaforma per servizi di KDD

Sommario La varietá degli strumenti e lo sviluppo continuo di nuove tecniche configura un sistema ideale di supporto alla progettazione di processi di KDD come un sistema aperto e modulare. Per raggiungere questi obiettivi, l’articolo presenta l’idea di un sistema di KDD come piattaforma, che sfrutta concetti e tecnologie sviluppati nell’ambito della computazione cooperativa ed in particolare d...

We study a particular class of rationally connected manifolds, X ⊂ P , such that two general points x, x′ ∈ X may be joined by a conic contained in X. We prove that these manifolds are Fano, with b2 6 2. Moreover, a precise classification is obtained for b2 = 2. Complete intersections of high dimension with respect to their multi-degree provide examples for the case b2 = 1. The proof of the cla...
