The HEART-MET<\/strong> cascade campaign results<\/h1>\n

In our recent campaign we took the opportunity to evaluate our dataset using state-of-the-art video classification models. These models were designed to identify and categorise actions in video clips. For this analysis, both Convolutional Neural Networks (CNNs) and Vision Transformer models were employed, covering a broad range of modern techniques in the field of video classification.<\/p>\n

The models used include:<\/p>\n

\n
1. I3D<\/strong>: Based on the Inception architecture, this model is enhanced to handle the temporal nature of videos by using 3D convolutions, which analyse both spatial and temporal dimensions.<\/li>\n
2. R2Plus1D<\/strong>: A ResNet-based model that separates the spatial and temporal convolutions, using 2D for spatial data and 1D for temporal features.<\/li>\n
3. S3D<\/strong>: A variant of the I3D model, which employs separable 3D convolutions to process the spatial and temporal aspects independently.<\/li>\n
4. Swin Transformers<\/strong> (Tiny, Small, and Base): These models rely on the transformer architecture, which processes spatio-temporal patches (or 3D tokens) from video clips. The models differ in size, with Tiny and Small being more compact than the Base model.<\/li>\n<\/ol>\n

   For all the models, we used pre-trained weights from the Kinetics-400 dataset, and only trained the final classification layers on our data. The results of this evaluation are summarised in the table below.<\/p>\n\n\n\n\n\n\n\n\n\n

This outcome was expected, as Dataset B was collected in a controlled environment, leading to more consistent data across training and testing phases. This consistency is beneficial for models to learn effectively, making it particularly useful in healthcare scenarios where robots must quickly adapt to the environment and individuals they interact with.<\/p>\n  <\/p>\n<\/div>\n<\/div><\/div><\/div> \n \n\t Coordination team:<\/strong><\/h3>\n Nico Hochgeschwender<\/strong><\/p>\n CONTACT:<\/strong><\/h3>\n healthcare(a)metricsproject.eu<\/a><\/p>\n  <\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":" The HEART-MET cascade campaign results In our recent campaign we took the opportunity to evaluate our dataset using state-of-the-art video classification models.
