在此之前,我们先看一下原始的 least square 问题的最优解(eq: 1)现在变成了什么样子,由于 orthonormal design ,我们有eq: 3 »wˆ=1nXTy然后我们再来看 LASSO ,假设wˉ=(wˉ1,…,wˉp)T是JL(w)的全局最优值点。考虑第j个变量wˉj,有两种情况。 gradient 存在,此时wˉj≠0 由于gradient 在最小...

MATLAB Online에서 열기 Ran in: An old question, so my answer is completely irrelevant to Benjamin. Sorry about being late on this. But the solution is not that difficult. First, don't use quadprog or quadratic programming for this. The simple solution uses lsqlin anyway. ...
