首先设置一个更适合有效近似的新层,引入门控机制来减轻自注意力的负担,产生了下图 2 中的门控注意力单元 (Gated Attention Unit, GAU)。与 Transformer 层相比,每个 GAU 层更便宜。更重要的是,它的质量更少依赖于注意力精度。事实上,小单头、无 softmax 注意力的 GAU 与 Transformers 性能相近。 虽然GAU 在...

模型的剩下部分则是一个GAU(gated attention unit)。最近的几个框架Mega、RWKV、retnet、mamba、本文的GLA等都用到了GAU,苏神推的GAU看上去非常promising)。这里的LN是group norm,即每个head分别norm。 S_{t} = G_{t} \odot S_{t-1} +K_{t}^{T}V_{t} \in R^{d_{k}×d_{v}}, O_{t} ...
对于FLASH模型,首先要了解的是它分为两个部分,分别是GAU(Gate Attention Unit)和MCA(Mixed Chunk Attention)这两部分,其中的GAU就是它的内核,而MCA则是一个优化它的办法。就像一台车一样,GAU是引擎,ACM则是其它部分,这二者的组合使得这辆车有着超高的性能。文章的结构就是按照这两大块进行的,其中穿插着一些前置...
Moreover, unlike Refs.21,22 which implemented graph neural network and graph attention network that made use of convolution of neighbouring nodes to significantly improve performance, we design a GRU architecture (henceforth referred to as DNNGRU) which leverages on temporal information to predict OD...

研究者首先提出了门控注意力单元(Gated Attention Unit, GAU),这是一个比 Transformers 更简单但更强的层。虽然 GAU 在上下文长度上依然具有二次复杂度,但它在下文展示的近似方法中更可取。 相关的层包括如下: 原版多层感知机(Vanilla MLP); 门控线性单元(Gated Linear Unit, GLU),它是门控增强的改进版 MLP...
Recently, the gated attention unit (GAU) was proposed. Compared with traditional multi-head self-attention, approaches with GAU are effective and computationally efficient. In this CGA-MGAN: MetricGAN based on Convolution-augmented Gated Attention for Speech Enhancement, we propose a network for ...
