 An action classification operator generates labels of human activities (with corresponding scores)
 and extracts features for the input video.
 It transforms the video into frames and loads pre-trained models by model names.
-This operator has implemented pre-trained models from [TimeSformer](https://arxiv.org/abs/2102.05095)
+This operator has implemented pre-trained models from [VideoSwinTransformer](https://arxiv.org/abs/2106.13230)
 and maps vectors with labels.

 ## Code Example
 
-Use the pretrained TimeSformer model ('timesformer_k400_8x224')
+Use the pretrained VideoSwinTransformer model ('swin_tiny_patch244_window877_kinetics400_1k')
 to classify and generate a vector for the given video path './archery.mp4' ([download](https://dl.fbaipublicfiles.com/pytorchvideo/projects/archery.mp4)).
