Oracle inequalities and the isomorphic method


We use the isomorphic method to study exact and non-exact oracle inequalities for empirical risk minimization in classes of functions that satisfy a subgaussian condition. We show that the “isomorphic profile” of the corresponding squared-loss classes may be characterized using properties of the gaussian process indexed by the underlying base class. We use… (More)
