The Global Average Pooling 1D Layer block performs downsampling by outputting the average of the time or spatial dimensions of the input.
2-D global average pooling layer expand all in page Description A 2-D global average pooling layer performs downsampling by computing the mean of the height and width dimensions of the input. The dimensions that the layer pools over depends on the layer input: ...
In this paper, we propose another strategy called global average pooling to replace the traditional fully connected layers in CNN. The idea is to generate one feature map for each corresponding category of the classification task in the last mlpconv layer. Instead of adding fully connected layers ...

池化方法(1):General / Mean / Max / Stochastic / Overlapping / Global Pooling CNN网络中常见结构是:卷积、池化和激活。卷积层是CNN网络的核心,激活函数帮助网络获得非线性特征,而池化的作用则体现在降采样:保留显著特征、降低特征维度,增大kernel的感受野。深度网络越往后面越能捕捉到物体的语义信息,这种语义信息...
池化层(pooling layer) 来源:Coursera吴恩达深度学习课程 除了卷积层,卷积网络也经常使用池化层(pooling layer)来缩减模型的大小(reduce the size of their representation),提高计算速度(speed up computation),同时提高所提取特征的鲁棒性(robust),下面来看一下。 上面是池化层的例子,假设输入是4×4矩阵,池化类型是...
深度学习系列 | Global Average Pooling是否可以替代全连接层? Global Average Pooling(简称GAP,全局池化层)技术最早提出是在这篇论文(第3.2节)中,被认为是可以替代全连接层的一种新技术。在keras发布的经典模型中,可以看到不少模型甚至抛弃了全连接层,转而使用GAP,而在支持迁移学习方面,各个模型几乎都支持使用Global...
