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...
本发明涉及一种面向水环境数据时间序列预测的方法,特别是涉及一种基于SG(Savitzky Golay)滤波与编码器解码器结构的稀疏注意力机制(ProbSparse SelfAttention Mechanism,PSAM)和多头注意力机制(MultiHead Attention Mechanism,MHAM)的单监测断面时序多要素... 张春辉,毕敬,乔俊飞 被引量: 0发表: 2023年 基于深度学习的...
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...
