The difference between LASSO1,1 Model, LASSO2,1 Model, and Our Proposed Model. The left panel represents the input datasets; the right panel represents the learned weight matrix. (A) Schematic of our method for feature selection. (B) Schematic diagram of feature selection based on multi-task Lasso model under ℓ1,1 regularization. (C) Schematic diagram of feature selection based on multi-task Lasso model under ℓ2,1 regularization.
