# How to get the solution and prediction of nuclear ridge regression? [closed]

$$$$\label{eqs.1} \tilde{y}=\sum_{m=1}^{M}\alpha_{m}\kappa(x^{(m)},\tilde{x}) (1)$$$$ where $$\kappa(x^{(m)},\tilde{x})$$defines the similarity between data and can be chosen beforehand.The weighting$$\alpha=(\alpha_{1},...,\alpha_{M})^{T}$$,for instance,can be determined by minimizing the least-square loss function $$$$\label{eqs.2} L(\alpha)=\sum_{m=1}^{M}(\tilde{y}^{(m)}-y^{(m)})^{2}+\chi\sum_{m=1}^{M}\alpha_{m}^{2} (2)$$$$ The combination of (1) and (2) is a kernel ridge regression. How to get the solution and prediction of nuclear ridge regression?
