Web1.重要的4个概念 （1）卷积convolution：用一个kernel去卷Input中相同大小的区域【即，点积求和】，最后生成一个数字。 （2）padding：为了防止做卷积漏掉一些边缘特征的学习，在Input周围围上几圈0。 （3）stride：卷积每次卷完一个区域，卷下一个区域的时候，向上或向下挪几步。 WebExample 1: Wrong Input Shape for CNN layer. Suppose you are making a Convolutional Neural Network, now if you are aware of the theory of CNN, you must know that a CNN (2D) takes in a complete image as its input shape. And a complete image has 3 color channels that are red, green, black. So the shape of a normal image would be (height, width ...
