We thank the reviewers for their comments and interest. R1 Assigned_Reviewer_1). R2 proposes a baseline method to compare with. Our interpretation of the comment is that in the expression Y - Z t beta _2, R2 uses Z to denote the feature-vector and Y a 0-1 label, so this proposal corresponds to standard least-squares regression (with lasso). Generally, logistic (lasso) regression is preferable for binary responses [1]. As we already evaluated our approach against the latter method (Figure 1b), the proposed comparison seems unnecessary given the space constraints.
