因果关系自回归模型:在自回归模型(如GPT系列)中,因果注意力机制(causal attention mechanism)通过限制每个元素只能与之前的元素进行交互,从而隐含地引入了位置信息。尽管显式的位置编码可以提高模型性能,但一些研究表明,即使没有显式位置编码,这类模型也能够学习到一定的位置信息。 特定的非序列任务:对于一些不依赖于元素...
the increased computational complexity, stemming primarily from the self-attention mechanism, parallels the manner in which convolution operations constrain the capabilities and speed of convolutional neural networks (CNNs). The self-attention algorithm, specifically the matrix-matrix multiplication...

In this research, we propose the sequence pair feature extractor, inspired by Bidirectional Encoder Representations from Transformers (BERT)'s sentence pair task, to obtain a dynamic representation of a pair of ECGs. We also propose using the self-attention mechanism of the transformer to d...
The main efficiency bottleneck in Transformer models is its self-attention mechanism. Here, each token’s representation is updated by attending to all other tokens in the previous layer. This operation is key for retaining long-term information, giving Transformers the edge over recurrent models on...
2.1 The attention mechanism in visual tasks 注意力机制可以看作是一种根据激活的重要性来重新分配资源的机制。它在人类视觉系统中起着重要的作用。在过去十几年中,该领域得到了蓬勃的发展[3] [13] [14] [15] [16] [17] [18]。Hu等人提出了SENet[15],表明注意力机制可以降低噪声,提高分类性能。随后,许...
