There is a keen interest, especially in scientific applications, to understand the why of model predictions. 2014 22nd European Signal Processing Conference (EUSIPCO). However, as an update of only one parameter group depends on all the parameter groups or data points, the computation cost is high when the number of the parameters or data points is large. Recent works also reveal its connections to some statistically sound and hyperparameter-free methods, e.g., group-sparse iterative covariance-based estimation (GSPICE). << /Resources 216 0 R A group Lasso model is constructed to represent the defect imaging problem, and formulated by a sparse Bayesian learning (SBL) framework, where a hierarchical model of a Laplace prior is built to represent the group Lasso regularization.

In other words, it assumes the model has a sparsity structure. Assuming a given group structure on patient samples by clinical information, sparse group selection on fused lasso (SGS-FL) identies the optimal latent CNV components, each of which is specic to the samples in one or several groups. Under certain mild assumptions and a properly chosen regularization term,we prove that the solution of the proposed approach is asymptotically consistent. /Published (2019) A regularized model for linear regression with 1 and2 penalties is introduced and it is shown that it has the desired effect of group-wise and within group sparsity. /Book (Advances in Neural Information Processing Systems 32) /Resources 14 0 R /Annots [ 131 0 R 132 0 R 133 0 R 134 0 R 135 0 R 136 0 R 137 0 R 138 0 R 139 0 R 140 0 R 141 0 R 142 0 R ] This work provides new safe screening rules for Sparse-Group Lasso and shows significant gains in term of computing time for a coordinate descent implementation. %~p[Udlm >> An ecien t algorithm is derived for the resulting convex problem based on coordinate descent that can be used to solve the general form of the group lasso, with non-orthonormal model matrices.

Gap Safe Screening Rules for Sparsity Enforcing Penalties. An original and computationally-efficient method is proposed here to solve the Lasso problem, based on a dynamic screening principle, which makes it possible to accelerate a large class of optimization algorithms by iteratively reducing the size of the dictionary during the optimization process. In this paper, an adaptive method based on complex Bayesian group Lasso is developed for localizing the damage. /Type /Page It efficiently skips the updates of the groups whose parameters must be zeros by using the parameters in one group.
