comment optimising problem - least mean square error
Yeah, I think I'm looking for the minimum distance between a line and a point in $\mathbb{R}^n$. But I need to know the corresponding value of $\eta$ as well not only the value of the minimum distance.

No I don't. Probably this is what I'm looking for..

comment optimising problem - least mean square error
I guess it is. My problem is I don't exactly know how to "understand" this problem. I also thought about taking it as a vector problem - a n-dimensional target vector is given and another vector is given which should be altered to be closer to the target vector, but only certain components following certain rules (depending on the $\mu$s) can be altered.

Yes, $\mu_1, \mu_2, \mu_3$ do not depend on $t$.
