La regularización de Tíjonov es el método de regularización usado más comúnmente. En algunos campos, también se conoce como regresión de arista . En su forma más simple, un sistema de ecuaciones lineales mal determinado: , donde es una matriz de dimensiones , es un vector vertical con celdas y es otro vector vertical con celdas, es ...
Also known as Tikhonov regularization, named for Andrey Tikhonov, it is a method of regularization of ill-posed problems. It is particularly useful to mitigate the problem of multicollinearity in linear regression, which commonly occurs in models with large numbers of parameters.
Learn how to use Tikhonov regularization and other methods to solve ill-posed inverse problems with kernel functions. See the derivation, properties and examples of Tikhonov regularization and its variants, such as ERM, gradient descent, truncated singular value decomposition and principal component regression.

Bayesian Regularization: From Tikhonov to Horseshoe. Nicholas G. Polson and Vadim Sokolovy. First Draft: November, 2018 This Draft: February, 2019. Abstract. Bayesian regularization is a central tool in modern-day statistical and machine learn-ing methods. Many applications involve high-dimensional sparse signal recovery problems.
