编辑:Daniel code:https://github.com/leaderj1001/Attention-Augmented-Conv2d 传统CNN中的卷积核只能关注局部特征,而self-attention则可以关注全局特征,本文作者将卷积特征图与通过mutil-head self-attention产生的一组特征图进行级联,以增强卷积算子。文章具体框架如下图: 对于输入特征图中的每个位置(h,w),分别其...
PyTorch 实现地址:https://github.com/leaderj1001/Attention-Augmented-Conv2d 其中包括两个版本的实现:
在取代卷积作为独立计算单元方面被证明是有竞争力的. 但是需要注意的是,在控制实验中发现, 将自注意力和卷积组合起来的情况可以获得最好的结果. 因此并没有完全抛弃卷积, 而是提出使用self-attention mechanism来增强卷积(augment convolutions), 即将强调局部性的卷积特征图和基于self-attention产生的能够建模更长距离依...

用自注意力增强卷积:这是新老两代神经网络的对话(附实现)PyTorch 实现地址:https://github.com/leaderj1001/Attention-Augmented-Conv2d PS:启示就是在卷积算子的基础上,加入了多个注意力head(每个自注意head就是no-local block。),然后将这些head concat到一起。

As shown in Figure 6, YOLOv4 uses CSPDarknet53 as the backbone, and then the three different scale features 𝐹𝐶∈(𝐶∈{𝐶3,𝐶4,𝐶5})FC∈(C∈{C3,C4,C5}) extracted from the backbone are augmented with contextual scale information using an FPN and a path aggregation network ...
