An octave-tree discrete wavelet transform is employed to induce sparsity within the image signal.
Furthermore, it imposed sparsity within the context of partial least squares and thereby carried out dimension reduction and variable selection simultaneously [ 21, 22].
Furthermore, the severity of the sparsity within X is compounded by the additional weighting required by the experts' inclusion into the HME architecture.
This choice of penalty parameters allows for strong grouping, leading to heavy group sparsity and intermediate sparsity within a selected gene, yet has the ability to select a wide range of causal gene configurations.

The sparse group lasso encourages sparsity between and within groups, and has been previously applied to GWAS for variants with frequencies [Zhou et al., 44].
Similarly, abnormal structures present in FTD-3 patient fibroblasts internalized EGFR despite some abnormal membrane deformation and sparsity of ILVs within the enlarged lumen.
AUDIENCE: Sparsity with respect to the weight.
If our desired signal, x, is sparse enough then it has been shown that the solution to (1) is the one with maximum sparsity which is unique (within some ϵ-ball around x) [26, 27].
The Sparse Group Lasso method is a combination of Lasso and Group Lasso, which can achieve sparsity between groups and within the group.
Therefore, it is more intuitive to discover the sparsity between channels and within each channel and then obtain the important features.
For the sparsity constraint, we tested λ within the range 1 × 10-11 to 1 × 10-2.
