Webb3 jan. 2024 · Introduction. The goal of PySlowFast is to provide a high-performance, light-weight pytorch codebase provides state-of-the-art video backbones for video … Webb相比于SlowFast在长视频的表现,TimeSformer高出10个点左右,这个表里的数据是先用k400做pretrain后训练howto100得到的,使用imagenet21k做pretrain,最高可以达到62.1%,说明TimeSformer可以有效的训练长视频,不需要额外的pretrian数据。 Additional Ablations Smaller&Larger Transformers Vit Large, k400和SSV2都降了1个点 相比vit base …
