 This optimization, commonly known as \emph{ridge regression}, reduces to a least squares fit for $\mu=\infty$. For finite $\mu$, ridge regression
 acts as a sort of ``Occam's razor'', favoring a \emph{parsimonious} model for $\beta$: among two vectors with the same square error, the one with the smallest norm is preferred.   This is consistent with the Gaussian prior on $\beta$, which implies that vectors with small norms are more likely. %In practice, ridge regression is known to give better prediction results over new data than model parameters computed through a least squares fit.

 TODO Explain the optimization problem, why it has to be formulated as an auction
 problem. Explain the goals:
