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...
同样的,我们也沿用Transformer中的前馈网络(Position-wise Feed-forward Network)、残差连接(Residual Connections)以及层标准化(Layer Normalization)。N个Transformer Block会被使用去加深网络。 最终,深度位置交叉模块会产出每个位置的深度非线性交叉表示,其中第 k 个位置被表示为r^{pos}_k。 2.3位置组合模块(Position-...
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 {De...
