卷积神经网络(convolutional neural network,CNN)是指至少在网络的一层中使用卷积运算来代替一般的矩阵乘法运算的神经网络,因此命名为卷积神经网络。那什么是卷积运算啊?接下来我们一起来揭开它神秘的面纱。 【卷积(Convolution)】 我们以灰度图像为例进行讲解:从一个小小的权重矩阵,也就是卷积核(kernel)开始,让它逐步...
If you wish however, you can work through this optional portion of the notebook to get a sense of what backprop in a convolutional network looks like. 553 # 554 # When in an earlier course you implemented a simple (fully connected) neural network, you used backpr...

所以就有了pooling这个方法,翻译作“池化”?感觉pooling这个英语单词还是挺形象的,翻译“作池”化就没那么形象了。其实也就是把特征图像区域的一部分求个均值或者最大值,用来代表这部分区域。如果是求均值就是mean pooling,求最大值就是max pooling。讲义中那个gif图也很形象,只是不知道这里怎么放gif图... 至于...
we simply pass them to a fully connected, simple neural network that combines them in order to classify the input image into classes. That is nearly all that there is to know about convolutional nets at a conceptual level (pooling procedures are important too, but that would be another blog...

Image created using gifify. Source: YouTube. Welcome back to deep learning! So today, we want to look a bit into how to process graphs and we will talk a bit about graph convolutions. So let’s see what I have here for you. Topic today will be an introduction to graph deep ...
