有一篇文章叫,on layer normalization in the transformer architecture,它问的问题就是 為什麼,layer normalization是放在那个地方呢,為什麼我们是先做,residual再做layer normalization,能不能够把layer normalization,放到每一个block的input,也就是说 你做residual以后,再做layer normalization,再加进去 你可以看到说...
Transformer教程系列介绍 大模型的发展正在逐渐从单一模态数据输入向多模态数据输入演进,文本、语音、图像、视频等多模态的联合训练学习,不同模态之间形成有效互补,这将有助于提升模型的效果和泛化能力,为迈向通用人工智能奠定更加坚实的一步。而提到多模态的算法模型,就不得不提到大名鼎鼎的 Transformer。 2017年, Google...
Convolution neural networks have achieved remarkable results in medical image segmentation in the past decade. Meanwhile, deep learning models based on Transformer architecture also succeeded tremendously in this domain. However, due to the ambiguity of the medical image boundary and the high complexity ...
因此这里虽然目标词是来源于decoder,但是整个计算过程和transformer中的self-attention是一致的。 decoder端:1)RNN RNN在解码时一般都是用单层,因为从左到右...最后一层的隐层状态用于之后计算attention。 attention端:1)RNN RNN的attention都是基于decoder中的目标词和encoder的序列中的每一个词计算点积(或者其他的...

原始版本的 Transformer 中,由于自注意力机制的影响,模型是不会计算位置信息的,所以原始论文为了加入位置距离信息,在word-embedding时加入了基于余弦函数的位置编码,但是,对于NER任务来说,距离信息和相对位置信息同样重要。比如,‘in’ 后面的词通常是地点或时间,‘Inc.’前面通常是机构名,而机构名也常常是一组词,所以...
To make medical image segmentation more efficient and accurate, we present a novel light-weight architecture named LeViT-UNet, which integrates multi-stage Transformer blocks in the encoder via LeViT, aiming to explore the effectiveness of fusion between local and global features together. Our ...
