thanks for your sharing.nice work.
but could you pls show your ablation experiment result? especially the cbam.
and could u pls tell me why you didn't use " c = qk.pow(2).sum(1).unsqueeze(1) “ in the code.
wait for your reply .

1. Haven't tried that before.
2. We will update the paper later on this. In short, the following softmax will cancel out this term.

Update: We tried without CBAM block and I would say that we don't really need it. We get -0.6 J&F in DAVIS and +0.1 global score in YouTubeVOS -- so nothing really significant. You are welcome to drop this block (see no_cbam branch).
