Kernel Ridge Regression 核岭回归 由于数据可能是非线性的,单纯的线性回归效果可能不是很好,因此可以把数据映射到一个核空间,使得数据在这个核空间里面线性可分。 设 核函数 为 Φ i = Φ (x i) 是 When there are many correlated predictors in a linear regression model, their regression coefficients can become poorly determined and exhibit high variance. Ridge regression is a classical statistical technique that attempts to address the bias-variance trade-off in the design of linear regression models. However, we can now replace the matrix K with a kernel function to do ridge regression in some other space, giving us a non-linear (and non A function for producing a krr (kernel ridge regression) model.

Optimal scaling is a possibility to improve the correlation between predictors and outcomes. Th e objective of the present research was to develop an R package for genomic prediction based on a maxi-mum likelihood (ML) or restricted maximum likelihood (REML) approach The ridge regression estimator is thus unaffected by the projection, as Px ˆβ(λ) = ˆβ(λ), and it must therefore already be an element of the projected subspace R(X).
