trained from scratch (Section 4.5), while most results of other papers or model zoo are fine-tuned from a pre-trained

We appreciate the reviewers for the constructive comments on this paper. One common concern is our baseline for RetinaNet/Mask-RCNN is not strong. ImageNet Pre-Training." is comparable with our baseline (39.5% vs 39.24%). R1Q1: How do the latencies change on GPU? R1Q2: The improvements are not large. R1Q3: Compare to prior BSS search methods like POP[22] in Table 1.
