该9步过程可以看作是一个矩阵跟另外一个矩阵的矩阵相乘将每步input拉直，例如左上角第一个深蓝色区域拉为332001312行向量，再将Kernel拉为$(012220012)^T$列向量相乘得到第一个最终结果的左上角第一个数值12.0So，上边九步运算可以视为行数为9的矩阵和列数为9的矩阵进行矩阵乘法，再将相乘的结果reshape为欲得到的结果Other Method实现一个长度为25的内积目前Kernel只是3×3的范围大小，若是将Kernel填充一下，eg.左上角第一幅图，Kernel只有9个数，但是我们可以脑补一下浅蓝色部分都填充为0，每一步都将Kernel填充浅蓝色部分为0，那么，原问题就变为25行向量和25列向量相乘。Coding希望把region_vector都放入到region_matrix中，再将region_matrix与Kernel_mat...

MODULECLASStorch.nn.Module(args, kwargs*)[SOURCE]层、模型的父类Base class for all neural network modules.Your models should also subclass this class.Modules can also contain other Modules, allowing to nest them in a tree structure. You can assign the submodules as regular attributes:import torch.nn as nn import torch.nn.functional as F class Model(nn.Module): def __init__(self): ...
