A solução da regressão kernel ridge ordinária, baseada na função de perda quadrática e no regularizador quadrático baseado em norma, pode ser facilmente interpretada como um estimador linear estocástico, considerando a autocorrelação anterior para uma função verdadeira desconhecida. Como é bem sabido, um estimador afim estocástico é uma das extensões mais simples do estimador linear estocástico. No entanto, o seu problema de regressão do kernel correspondente não foi revelado até agora. Neste artigo, damos uma formulação do problema de regressão kernel, cuja solução é reduzida a um estimador afim estocástico, e também damos interpretações da formulação.

Abstract: The solution of the ordinary kernel ridge regression, based on the squared loss function and the squared norm-based regularizer, can be easily interpreted as a stochastic linear estimator by considering the autocorrelation prior for an unknown true function. As is well known, a stochastic affine estimator is one of the simplest extensions of the stochastic linear estimator. However, its corresponding kernel regression problem is not revealed so far. In this paper, we give a formulation of the kernel regression problem, whose solution is reduced to a stochastic affine estimator, and also give interpretations of the formulation.
