General nonexact oracle inequalities for classes with a subexponential envelope
Statistical learning fast rates of convergence oracle inequalities regularization classification aggregation model selection
2012/6/21
We show that empirical risk minimization procedures and regularized empirical risk minimization procedures satisfy nonexact oracle inequalities in an unbounded framework, under the assumption that the...
In this paper we describe General Covariance Union (GCU) and show that solutions to GCU and the Minimum Enclosing Ellipsoid (MEE) problems are equivalent.
Extended Generalized-K (EGK): A New Simple and General Model for Composite Fading Channels
Extended Generalized-K General Model
2011/1/4
In this paper, we introduce a generalized composite fading distribution (termed extended generalized-K (EGK)) to model the envelope and the power of the received signal in millimeter wave (60 GHz or a...
