Nettet5. jul. 2024 · Let X and Y be Hilbert spaces. Further, let T\in \mathcal {L} (X,Y) and assume R ( T) to be non-closed in Y . Here we recall the regularization of the ill-posed problem Tx = y δ in a nutshell. For more details see standard textbooks, e.g., [ 58, 108, 121, 148 ]. The task is to find a meaningful approximation to x + ∈ N ( T) ⊥ knowing only ... NettetWe propose regularization methods for linear models based on the Lq-likelihood, which is a generalization of the log-likelihood using a power function. Regularization methods are popular for the estimation in the normal linear model. However, heavy-tailed errors are also important in statistics and machine learning. We assume q-normal distributions as …

NettetThis model solves a regression model where the loss function is the linear least squares function and regularization is given by the l2-norm. Also known as Ridge Regression or Tikhonov regularization. This estimator has built-in support for multi-variate regression (i.e., when y is a 2d-array of shape (n_samples, n_targets)).
