A novel model, named Self-Attention Fusion Networks (SAFN) is proposed. First, the multi-head self-attention mechanism is utilized to obtain the sentence and the aspect category attention feature representation separately. Then, the multi-head attention mechanism is used again to fuse these two ...
In this paper, we start from these two aspects, and we propose a self-attention feature fusion network for semantic segmentation (SA-FFNet) to improve semantic segmentation performance. Specifically, we introduced the vertical and horizontal compression attention module (VH-CAM) and the unequal ...

论文阅读《Self-Attention Guidance and Multiscale Feature Fusion-Based UAV Image Object Detection》 Tywwhale 1 人赞同了该文章 摘要 无人机(UAV)图像的目标检测是近年来研究的热点。现有的目标检测方法在一般场景上取得了很好的结果,但无人机图像存在固有的挑战。无人机图像的检测精度受到复杂背景、显著尺度差异...
In this paper, we integrate both soft and hard attention into one context fusion model, "reinforced self-attention (ReSA)", for the mutual benefit of each other. In ReSA, a hard attention trims a sequence for a soft self-attention to process, while the soft attention feeds reward signals ...
之后第二步,输入BERT框架使用self-attention机制(没有做改造)逐层更新表示层: 逐层更新 也就是说,此处的BERT仅仅是将位置信息作为了side信息,并且使用addition作为fusion函数。 NOVA-BERT框架 之前提过NOVA的核心修改自我注意机制,仔细控制自已组件的信息源,即Q、K和V。
另一方面,研究人员也挑战了Self-Attention的必要性。MLP-Mixer也建模了全局依赖关系,但它采用了一个MLP块,而不是一个自注意模块来实现。MLP-Mixer的整体架构与ViT相似。输入图像被分成多个patch,然后线性层将patch映射到token中。该编码器包含用于空间混合和通道混合的交替层。
A self-attention mechanism can capture long-range dependencies by calculating the interaction between any two positions of the feature map. • Spectral normalization is applied to stabilize the training of thediscriminatornetwork. Abstract The application of adversarial learning for semi-supervisedsemantic...
在这项工作中,作者探究了Transformer的自注意(Self-Attention)模块是否是其实现图像识别SOTA性能的关键 。为此,作者基于现有的基于MLP的视觉模型,建立了一个无注意力网络sMLPNet。具体来说,作者将以往工作中用于token混合的MLP模块替换为一个稀疏MLP(sMLP)模块。对于二维图像token,sMLP沿轴向(横向或者纵向)应用一维MLP...
