CNN 是一种特殊的神经网络,专门用于处理图像数据。在 CNN 中,矩阵乘法用于计算卷积核中的权重和偏置。 机器学习 在机器学习中,矩阵乘法也常常用于矩阵运算,例如矩阵乘法在循环神经网络(RNN)中用于计算隐藏层的权重。 信号处理 在信号处理中,矩阵乘法可以用于将一个时域信号乘以一个频域信号,从而得到一个新的时域信号...
For larger matrix operations we recommend optimized software packages likeNumPywhich is several (in the order of 1000) times faster than the above code.

Thus, there is a function dot, both an array method and a function in the numpy namespace, for matrix multiplication: In [223]: x = np.array([[1., 2., 3.], [4., 5., 6.]]) In [224]: y = np.array([[6., 23.], [-1, 7], [8, 9]]) In [225]: x Out[225]: ...
