The proposed group bilinear requires the intra-group channels to be highly5 correlated (refer tothedefinitioninQ3.1),andtheproposed semantic grouping canbetter satisfy suchrequirements6 than MA-CNN [9]. Specifically,[9] adopts the idea of k-means, which optimizes each channel to its cluster center.7 Note that the notations aboveare the same with Eqn.16 (3),andthepairwisecorrelationis dij = Thanks foryour comments.Aisanapproximate indexmapping20 matrix, whose rows are constrained to be (approximate) one-hot vectors via asoftmax with small "temperature".21 Q2.2Inconsistentnotations. Thanks for your comments, and we will correct the notation "stage 3,4" into "Stage28 IV,V"respectively. Designing suitable grouping methods plays a42 keyrole.
