The model consists of a 3D CNN multi-stage feature extraction module, followed by a classification head. It achieves state-of-the-art results on the UCF101 dataset.  _**Figure 1** Model architecture_ ## 2 Pretrained Models ### 2.1 TUC-AR Dataset [Dataset Homepage](https://huggingface.co/datasets/SchulzR97/TUC-AR) **Short Description** - RGB and depth input recorded by Intel RealSense D435 depth camera - 7 subjects - 3 perspectives per sequence - 11,031 sequences (train 8,893/ val 2,138) - 6(+1) action categories **Input** | Dimension | Fixed | Value | Parameter | Description | |-----------|---------|-------|-----------------|-------------------------------------------| | 0 | no | ? | Batch Size | Number of samples that will be propagated through the network (number of sequences) | | 1 | yes | 30 | Sequence Length | Number of frames in one sequence | | 2 | yes | 4 | Input Channels | Number of channels of one frame (RGB+D=4) | | 3 | yes | 400 | Width | Width of one frame | | 4 | yes | 400 | Height | Height of one frame | **Output** | Dimension | Fixed | Value | Parameter | Description | |-----------|---------|-------|-----------------|-------------------------------------------| | 0 | no | ? | Batch Size | Number of samples that will be propagated through the network (number of sequences) | | 1 | yes | 10 | Number of action classes | Number of action classes<br>0 - None<br>1 - Waving<br>2 - Pointing<br>3 - Clapping<br>4 - Follow<br>5 - Walking<br>6 - Stop | **Usage** ```python from huggingface_hub import HfApi api = HfApi() model_path = api.hf_hub_download('SchulzR97/TUC-AR-C3D', filename='tuc-ar.pth') model = torch.load(model_path) ``` ### 2.2 UCF101 Dataset [Dataset Homepage](h...
