简单来说,将输入特征分成几组,每组分别进行不同窗口大小的self-attention(SA),最后将各组进行合并处理。这样根据算力灵活调整组窗口大小。除此之外,还有一些小操作加速SA的运算(ASA,Accelerated self-attention):去除layer normalization(LN),因为LN将SA的计算分解为许多元素级运算,将LN替换成BN;同时,将SA的embedded G...
Moreover, attention models, encouraged by the human visual system, have emerged as crucial modules in diverse applications including natural hazard assessment. Therefore, we suggest a novel and intelligent generalized efficient layer aggregation network (GELAN) based on two prevalent attention modules,...

attention localization network 定位多个parts,利用基础的卷积特征映射对每一个part都产生一个score map。每一个score map 都是由两层累积的卷积层和一个spatial softmax layer构成。第一个卷积层利用64个3*3的kernel,第二层利用一个3*3的kernel来产生一个单通道的置信图。spatial softmax layer作用于confidence ma...

need for a novel approach that can harness the strengths of both DB and RL, along with advanced attention mechanisms, to set a new benchmark in image denoising. Dense blocks CNNs consist of three components: input layer, hidden layer, and output layer. The main structure of the hidden ...
