Preventing Over-Fitting during Model Selection via Bayesian Regularisation of the Hyper-Parameters A comparison of automatic techniques for estimating the Regularisation parameter in non-linear inverse problems
An important characteristic of Lasso Regression is that it tends to completely eliminate the weights of the least important features (i.e., set them to zero). For example, the dashed line in the right plot on looksquadratic, almost linear: all the weights for the high-degree polynomial featu...
Regression modelling beyond the mean of the response has found a lot of attention in the last years. Expectile regression is a special and computationally
In linear regression, only ordered dimensions are augmented by default with augmentation=on; in ridge regression where model=rl, only measures are augmented by default. To override the setting and disable augmentation for each predictor in your calculation, use augmentation=off; no higher order polyn...
The properties of L1-penalized regression have been examined in detail in recent years. I will review some of the developments for sparse high-dimensional data, where the number of variables p is potentially very much larger than sample size n. The necessary conditions for convergence are less ...
the coefficients in the model whereas lasso does this along with automatic variable selection for the model. this is where it gains the upper hand. while this is preferable, it should be noted that the assumptions considered in linear regression might differ sometimes. both these techniques tack...

We show that many, including the most popular, quasi-Newton methods can be interpreted as approximations of Bayesian linear regression under varying prior assumptions. This new notion elucidates some shortcomings of classical algorithms, and lights the way to a novel nonparametric quasi-Newton method,...
