Do you have any sources that expands on how that LASSO optimization problem was graphed?
My thoughts when I looked at it: Where did beta come from? Whats the beta hat supposed to represent? Where'd the contours come from? How come they stopped there? Oh they're supposed to represent the weights? How do they represent the weights? Why is LASSO diamond, the other circular?
I remember seeing that graph a while ago, didn't understand it then, still don't understand it now.
