位置逐元素前馈(position-wise feed-forward)在Transformer架构中被广泛使用,可以放在自注意力(self-attention)层之后,它的主要目的是在每个序列的位置单独应用一个全连接前馈网络。 自注意力子层用于捕捉序列中的长距离依赖关系,而位置逐元素前馈子层则用于学习局部特征,二者可以配合使用。例如,在GPT(基于Transformer的解...
2. 深度位置交叉网络(Deep Position-wise Interaction Network) 本节主要介绍深度位置交叉网络(Deep Position-wise Interaction Network)(DPIN)模型。如图4所示,DPIN模型由三个模块组成,分别是处理 J 个候选广告的基础模块(Base Module),处理 K 个候选位置的深度位置交叉模块(Deep Position-wise Interaction Module)以...
bidirectional mask strategysentence encoderTransformers have been widely studied in many natural language processing (NLP) tasks, which can capture the dependency from the whole sentence with a high parallelizability thanks to the multi-head attention and the position-wise feed-forward network. However...

In this paper, we propose the first hardware accelerator for two key components, i.e., the multi-head attention (MHA) ResBlock and the position-wise feed-forward network (FFN) ResBlock, which are the two most complex layers in the Transformer. Firstly, an efficient method is introduced to...

For CNN, a max pooling layer can be used to select the maximum value for each dimension and generate one semantic vector (with the same size as the convolution layer output) to summarize the whole sentence, which is processed by a feed-forward network (FFN) to generate the final sentence ...
The decoder is similar to DETR decoder, with a stack of L decoder layers that is composed of self-attention, cross- attention , and feed-forward network (FFN). The l-th decoder layer is formulated as follows, \mathbf {O}_{l} = \operatorname {Dec...
我们在__init__方法中就已经获取了全部的所需函数,所以,接下来直接搭建Forward即可! def forward(self, x): x = self.linear1(x) x = self.relu(x) x = self.dropout(x) x = self.linear2(x) return x 到这里一个Position Wise Feed Forward就ok了~ 4. Q&A Q1:为什么需要dropout,不写不能工作...
