Action Classification
What's this?
A benchmark of video action classification for common CNN architectures. Implemented in PyTorch v1.2, recent version should also work.

Notes
- benchmarks will come soon
Link
- ResNet-2d3d is used in SlowFast, DPC, etc.
- ResNet-3d is used in many papers, early ones like Hara et al.
- I3D from Carreira and Zisserman
- S3D/S3D-G from Xie et al.
