In my experience, regularization is applied on a complex/sensitive model to reduce complexity/sensitvity, but never on a simple/insensitive model to increase complexity/sensitivity.Thu, 02 Apr 2026 06:43:00 GMThttps://stats.stackexchange.com/questions/168666/boosting-why-is-the-learning-rate-called-a-regularization-parameterThe learning rate parameter ($\nu \in [0,1]$) in Gradient Boosting shrinks the contribution of each new base model -typically a shallow tree- that is added in the series. It was shown to dramaticallyFri, 03 Apr 2026 23:17:00 GMThttps://stats.stackexchange.com/questions/269298/why-do-we-only-see-l-1-and-l-2-regularization-but-not-other-normsThe intuition behind regularization is that I have some vector, and I would like that vector to be "small" in some sense. How do you describe a vector's size? Well, you have choices: Do you count how many elements it has $ (L_0)$? Do you add up all the elements $ (L_1)$? Do you measure how "long" the "arrow" is $ (L_2)$?Tue, 31 Mar 2026 11:03:00 GMThttps://stats.stackexchange.com/questions/260649/what-are-regularities-and-regularizationIs regularization a way to ensure regularity? i.e. capturing regularities? Why do ensembling methods like dropout, normalization methods all claim to be doing regularization?Mon, 02 Mar 2026 08:31:00 GMThttps://stats.stackexchange.com/questions/609970/l1-l2-double-role-in-regularization-and-cost-functionsRegularization - penalty for the cost function, L1 as Lasso & L2 as Ridge Cost/Loss Function - L1 as MAE (Mean Absolute Error) and L2 as MSE (Mean Square Error) Are [1] and [2] the same thing? or are these two completely separate practices sharing the same names? (if relevant) what are the similarities and differences between the two?Sat, 28 Mar 2026 13:58:00 GMThttps://stats.stackexchange.com/questions/674741/why-would-regularization-reduce-training-errorAn answer on this very site states that "regularization (including L2) will increase the error on training set" so observing the obverse is certainly noteworthy.Mon, 16 Mar 2026 14:20:00 GMThttps://stats.stackexchange.com/questions/141555/how-does-regularization-reduce-overfittingA common way to reduce overfitting in a machine learning algorithm is to use a regularization term that penalizes large weights (L2) or non-sparse weights (L1) etc. How can such regularization reduceSun, 05 Apr 2026 12:30:00 GMThttps://stats.stackexchange.com/questions/663570/difference-between-weight-decay-and-l2-regularizationI'm reading [Ilya Loshchilov's work] [1] on decoupled weight decay and regularization. The big takeaway seems to be that weight decay and $L^2$ norm regularization are the same for SGD but they are different for Adam.Thu, 19 Mar 2026 03:53:00 GMThttps://stats.stackexchange.com/questions/184019/when-will-l1-regularization-work-better-than-l2-and-vice-versaNote: I know that L1 has feature selection property. I am trying to understand which one to choose when feature selection is completely irrelevant. How to decide which regularization (L1 or L2) to...Fri, 03 Apr 2026 14:13:00 GMThttps://stats.stackexchange.com/questions/234280/is-tikhonov-regularization-the-same-as-ridge-regressionTikhonov regularization and ridge regression are terms often used as if they were identical. Is it possible to specify exactly what the difference is?Wed, 25 Mar 2026 02:28:00 GMT
