BYOL与SimSiam - 知乎

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 … Webb19 mars 2024 · Description: Implementation of a self-supervised learning method for computer vision.
