• Tichonow regularization to approximate a semi-definite matrix by a positive definite matrix
• Ridge regression in statistics, see Least Squares Method
• Regularization of matrices by adding additional rows and columns, see margin #Regularization
• Regularization in geometric modeling by converting a non-regular set into a regular set
• Regularization of degenerate differential equations by approximation with non-degenerate differential equations, see partial differential equation
• Regularization of underdetermined systems to determine the inverse, see inverse problem
• Regularize a group of machine learning methods to avoid overfitting
• Regularization in physics for the treatment of occurring infinities in quantum field theory, see renormalization #regularization
