The most striking result is observed with Laplace prior, where many of the coefficients end up to be zero. Indeed, it is said that Laplace regularization leads to sparse coefficient vectors and logistic regression with Laplace prior includes feature selection [2][3]. In the case of Gauss prior...

In this paper, we proposed a novel Gaussian weighted Laplace prior (GWLP) regularization method. It considered the variance of the bioluminescence energy between any two voxels inside an organ had a non-linear inverse relationship with their Gaussian distance to solve the over-smoothed tumor ...
That is, one should experiment with different Laplace's options (hessian_factorization, prior precision tuning method, predictive method, backend, etc!). Try looking at various papers that use Laplace for references on how to set all those options depending on the applications/problems at hand. ...

This component Σ(i) = Σ(λ)(i) is treated as an empirical prior on θ(i). spm_ReML.m uses Eq. (27) to estimate the requisite hyperparameters. Critically, it takes as an argument the matrix yyT. This may seem computationally inefficient. However, there is a special but very common...
