Webb2 jan. 2024 · SimSiam的理论解释意味着带stop-gradient的孪生网络表征学习都可以用EM算法解释。 stop-gradient起到至关重要的作用，并且需要一个预测期望E的方法进行辅助使用。但是SimSiam仍然无法解释模型坍塌现象，SimSiam以及它的变体不坍塌现象仍然是一个经验性的观察，模型坍塌仍然需要后续的工作进一步讨论。看懂了SimSiam对孪生网络 … WebbSimSiam可以视为是SimCLR去掉负样本。为了进一步对比，作者对SimCLR加上了predictor和stop-grad结构，效果没有提升：与SwAV对比 SimSiam可以视为SwAV去掉online clustering。作者同样对SwAV做了一些对比：加入predictor依然没有提升，同时去掉stop-grad之后导致模型无法收敛。与BYOL对比 SimSiam可以视为是BYOL去掉了动量编 …
