Regularization

Under regularization refers to various techniques for treating singularities or ill-conditioned problems:

• In the Tikhonov regularization a positive semi- definite matrix for arbitrarily small regularization by the positive definite (and hence invertible ) matrix is approximated. In statistics, this method is also called ridge regression.
• Lining means are ill-conditioned matrices regularized by adding additional rows and columns.
• In the theory of degenerate PDEs regularization means a method in which a degenerate differential equation by means of a non- degenerate one (i.e. regularized ) approximates the differential equation.
• In an inverse problem is solved by the regularization under certain system corrected such that the inverse can be determined.
• In physics, regularization is a formal method in the context of renormalization of a quantum field theory for the treatment of infinities occurring.
