WebThe Vision Transformer model represents an image as a sequence of non-overlapping fixed-size patches, which are then linearly embedded into 1D vectors. These vectors are then treated as input tokens for the Transformer architecture. The key idea is to apply the self-attention mechanism, which allows the model to weigh the importance of ...
