Two referees support accept, one weak-accept and one indicates reject. Rebuttal clarified R3’s concerns regarding two related work directions, but R3 did not respond during the reviewer discussion. R4 (weak-accept) did engage and was happy with the rebuttal connected with their concerns. R1 and R2 were happier with their accept stance post-rebuttal. I therefore think that this paper should be accepted. However, please consider closely proof-reading your paper for clarity and correctness.
