Abstract: We discuss the properties of a large class of learning algorithms defined in terms of classical regularization operators for ill-posed problems. This class includes regularized least-squares, Landweber method and truncated singular value decomposition over hypothesis spaces defined as reproducing kernel Hilbert spaces of vector-valued functions.
A minimax analysis for convergence rates over suitable priors will be presented, together with data-dependent choices of the regularization parameter enforcing statistical adaptation.
