ICCV 2021 | Vision Transformer中的相对位置编码 相对位置编码(RelativePosition Encoding)能够显式地对Transformer输入序列中,任意两个Tokens的位置关系进行建模。近来,中山大学与微软亚洲研究院的研究人员回顾了先前相对位置编码的相关工作,针对Vision Transformer,提出了简单且轻量的二维相对位置编码。在不需要调整任何训练...
采用了relative position encoding,所以计算公式可以表示为: 这种位置编码的引用[48,41]分别是: [48] Peter Shaw, Jakob Uszkoreit, and Ashish Vaswani. Self-attention with relative position representations. arXiv preprint arXiv:1803.02155, 2018. [41] Ze Liu, Yutong Lin, Yue Cao, Han Hu, Yixuan We...
To this end, we propose an efficient self-attention mechanism along with relative position encoding that reduces the complexity of self-attention operation significantly from O(n2) to approximate O(n). A new self-attention decoder is also proposed to recover fine-grained details from the skipped ...

As a stronger assessment of the relative effectiveness of the two representations, we conducted a further experiment requiring participants to select between adversarial images generated by the two models. Using each of the models, we generated adversarial examples from an image of a true classTand ...
Encoding Network that fuses deep channel attention information with shallow spatial attention information, merging semantic features and spatial details. AFF37is used for feature fusion in both short and long skip connections. This module learns the relative attention weights between feature planes of ...
