Element-wise multiplicationis where each pixel in the output matrix is formed by multiplying that pixel in matrix A by its corresponding entry in matrix B. The input matrices should be the same size, and the output will be the same size as well. This is achieved using themul()function: ...
也就是常说的elementwise,需要两个矩阵的大小一样(如果不考虑broadcast的话),multiply函数将两个矩阵相同位置的元素分别相乘,或者直接使用* import numpy as np a = np.array( [ [ 1,2 ], [ 3,4 ] ] ) b = np.array( [ [ 1,2 ], [ 3,4 ] ] ) ...
对应元素逐个相乘
相加的两个tensor通常都是具有特征意义的tensor,相乘的话,一般来说,其中一个tensor是有类似权重的含义...
逐元素相乘
同位元素对应相乘已经很直观了啊
