主要的更新在左边的encoder部分,其中是使用了prob-sparse注意力机制,代替了conformer中本来使用的 "香草“self-attention。 一,encoder编码器 左边的橙色部分。包括了下采样和位置编码层(注意,本文中使用的不是relative positional embedding)。然后就是若干conformer blocks。 使用公式表示就是: 编码器,x是输入的acoustic...
ProbSparse Self-attention (Informer) 考虑注意力系数的稀疏性 sparsity measurement 考虑注意力系数的分布(通常是长尾的)和均匀分布的KL散度 ProbSparse self-attention 其中Q¯为通过稀疏性度量得到的稀疏矩阵 LogSparse Attention 考虑融入局部特征 s each cell only to attend to its previous cells with an expon...
航空发动机剩余寿命预测对其健康管理具有重要意义,针对长序列,多维度的航空发动机监测参数,提出一种基于概率稀疏自注意力(ProbSparse Self-Attention)的Transformer模... 王欣,黄佳琪,许雅玺 - 《科学技术与工程》 被引量: 0发表: 2024年 针对特征过少地区冰雹强度的长时间序列预测方法 模型进行改进,提出一种应用于气...
Multi-head ProbSparse self-attentionStock trading strategyReinforcement learning is widely used in financial markets to assist investors in developing trading strategies. However, most existing models primarily focus on simple volume-price factors, and there is a need for further improvement in the ...
However, the time and memory complexity of self-attention increases squarely with the length of the sentence. In this paper, a prob-sparse self-attention mechanism is introduced into Conformer to sparse the computing process of self-attention in order to accelerate inference speed and reduce space...
Prob Attention的代码实现 Attention Layer 首先是一个基础Attention Layer,prob attention 就是通过这边的self.inner_attention来调用的 这么写的好处是方便做变体实验,如果要改成full attention,只需要改一下self.inner_attention就可以 classAttentionLayer(nn.Module):def__init__(self,attention,d_model,n_heads,d...
