LSLDA with concept drift4.1. Our rank-one update method for LSLDA. As previously discussed, the least squares LDA solution W can be computed as [9] (12) W = (A ⊤ A) − 1 A ⊤ Y. TīmeklisThis inverse problem is basically a least square problem with a rank-1 update. x = [ u v T + H H H] − 1 H H b. There are two objectives, one can be achieved with the least square problem and the other with the rank-1 update. I need to find the best tradeoff between the two. The least square solution (without the rank-1 update) needs to be ...

Tīmeklis2024. gada 6. okt. · For the few-quadratics case, there are solvers that rely on repeated multiplications of the form $\frac{1}{n-1}(M^TM-n\mu\mu^T)v$. These multiplications can be done cheaply without forming $\frac{1}{n-1}(M^TM-n\mu\mu^T)$ explicitly. Where to find a software package that does this, though, I'm not sure. $\endgroup$ –
