Where the article explains it
where A is the forward projection operator, b the measured data, L a penalty operator (often favoring smoothness), and > 0 a regularization parameter controlling the trade-off.
The passage around this formula
where A is the forward projection operator, b the measured data, L a penalty operator (often favoring smoothness), and > 0 a regularization parameter controlling the trade-off. As 0 the solution approaches the raw, noise-amplifying least-squares fit; as grows the solution…
