Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0029] For the convenience of the following description, let x=(x i,j,k ) H×H×W Represents a set of feature maps with N channels and a size of H×W, where H and W represent the number of rows and columns of a two-dimensional matrix, respectively. x i Denotes the feature map of the i-th channel, x i,j,k Represents the normalized element of row j and column k in the i-th channel, and has, i∈[1,N],j∈[1,H],k∈[1,W]. Note that since the number of convolution kernels in each layer is different, the number of feature map channels N of the input and output of each convolution layer changes....
