This is helping me with my research, thank you for uploading valuable content! I have one question with the soft threshold: the argmin in orange contains only a quadratic term and the l1 norm, but F(x,z,y) contains these and an extra term -yTz. I am having trouble applying the general soft threshold you defined with u and lambda to the main problem...thanks in advance
Thank you so much for your explanation. Excellent videos. I am facing a problem in which I want to apply the ADMM algorithm but I have inequalities and equalities constraints. Is it possible to do it? Thank you in advance.
I think we can use z as it is the sparse estimation with feature selection. But my supervisor thought we should use x and round off the small values as feature selection. So, I am confused which one refer to. @@MichaelZibulevsky
Thank you for your great videos. They are really helpful. Could you share a video about duality theorems related to perturbation and conjugate functions?

Thank you so much for video. I want to ask in this case; should we refer to x or z as estimators in lasso regression?
You may say in this way. What are you thinking of this?

should be A^Tb+pz-y?
You are right. The equation for Z(bar) also needs the opposite sign
Exactly, even within the inverse we have plus rho I
