例如在transformer的decoder层中,我们就用到了masked attention,这样的操作可以理解为模型为了防止decoder在解码encoder层输出时“作弊”,提前看到了剩下的答案,因此需要强迫模型根据输入序列左边的结果进行attention。 Masked的实现机制其实很简单,如图: 图7: Masked Attention 首先,我们按照前文所说,正常算attention sco...

Improving Transformers with Dynamically Composable Multi-Head Attention 1. 研究和理解动态可组合多头注意力的原理和优势 原理: 动态可组合多头注意力(Dynamically Composable Multi-Head Attention, DCMHA)旨在解决Transformer中多头注意力(MHA)的固有缺陷,如低秩瓶颈和头冗余问题。DCMHA通过动态组合不同的注意力头来提高...
As we discussed in Part 2, Attention is used in the Transformer in three places: Self-attention in the Encoder — the input sequence pays attention to itself Self-attention in the Decoder — the target sequence pays attention to itself Encoder-Decoder-attention in the Decoder — the ...
On the NLP4IF 2019 sentence level propaganda classification task, we used a BERT language model that was pre-trained on Wikipedia and BookCorpus as team ltuorp ranking #1 of 26. It uses deep learning in the form of an attention transformer. We substituted the final layer of the neural ...

Besides, the multi-head attention mechanism in Transformers has remarkable effect on model performance improvement by allowing the model to learn diverse features from multiple parallel subspaces (Vaswani et al., 2017). Inspired by these outstanding works, we propose a novel architectural unit, Multi...
