Web1 Jun 2009 · The Dantzig selector performs variable selection and model fitting in linear regression. It uses an L1 penalty to shrink the regression coefficients towards zero, in a similar fashion to the lasso. While both the lasso and Dantzig selector potentially do a good job of selecting the correct variables, they tend to overshrink the final coefficients. Web5 Apr 2024 · It is worth noting that we use the norm to characterize the group sparsity in the group Dantzig selector so as to achieve the high efficiency of the V-CQ algorithm. Indeed, the feasible sets C j and Q j in ( 3.6 ) are polyhedrons, and thus, it follows from corollary 2.6 that the V-CQ algorithm linearly converges to a feasible solution of ( 3.6 ). mohawk flooring burnished brown oakWebthe Gauss–Dantzig selector which uses the original Dantzig selector for variable selection and then runs ordinary least squares on the selected variables.
