ASFormer: Transformer for Action Segmentation

1 code implementation16 Oct 2021 Fangqiu Yi, Hongyu Wen, Tingting Jiang

However, there are several major concerns when directly applying the Transformer to the action segmentation task, such as the lack of inductive biases with small training sets, the deficit in processing long input sequence, and the limitation of the decoder architecture to utilize temporal relations among multiple action segments to refine the initial predictions.
