- (Major) Despite the elegant framework proposed, some implementation details may lack clarity and require further justification; please see the “questions” section below;
- (Major) The technical method for minimizing mutual information (MI) in the proposed IB-based CBM method is actually not so novel and largely relies on existing methods such as [1];
- (Major) The comparison between the two IB implementations appears somewhat simplistic and may provide only limited insights. What makes the estimator-based implementation more useful than the other?
- (Minor) While the presentation is generally good, some content could be more concise and structured. For instance, the derivation in Section 3.1 could be streamlined to present only the essential final estimator used in practice, relegating the full derivation to the appendix;
- (Minor) The main experimental results are based on only three runs. While I appreciate the author’s transparency in reporting this, more runs could be considered for better robustness of the results;
- (Minor) When assessing intervenability, a comparison between the proposed CIBM method and the original CBM is lacking. How CIBM exactly helps in improving intervenability does not seem apparent.
- (Minor) Reproducibility: despite the very interesting and elegant proposal, no code repo is shared. Together with the missing technical details mentioned above, this weaken the reproducibility of the work.
- (Minor) The main experimental results are based on only three runs. While I appreciate the author’s transparency in reporting this, more runs could be considered for better robustness of the results;
