WebbSlowFast 网络介绍. SlowFast ... Slow 路径可以是任何卷积模型，例如时空残差网络，C3D，I3D，Non-local网络等。Slow 路径的关键概念是输入帧上的大时间跨度τ(这里的"大"是指时间维度的步长较fast路径更长些)，即它只处理τ帧中的一个。 WebbarXiv:1912.00998v2 [cs.CV] 10 Jun 2024 A Multigrid Method for Efficiently Training Video Models Chao-Yuan Wu1,2 Ross Girshick2 Kaiming He2 Christoph Feichtenhofer2 Philipp Kra¨henbu¨hl1 1The Universityof Texas at Austin 2Facebook AI Research (FAIR) Abstract
