大家可能会注意到,现在神经网络中越来越多的设计会引入element-wise multiplication这个操作(我们后面就叫star操作,因为在python中符号就像星星一样)。不管是自然语言爆火的Mamba, GLU, 还是计算机视觉的FocalNet,VAN, HorNet等等,并且都取得了很好的效果。那么为什么star效果好呢?很多文章中都提出了自己

Perform element-wise multiplication using broadcasting: NumPy automatically broadcasts the reshaped arrays to a compatible shape and performs element-wise multiplication. Print the reshaped arrays and the result: This step prints the reshaped arrays x_reshaped and y_reshaped.For...
This is a very nasty bug: in an element-wise multiplication, the output values may be plausible, but turn out to be completely wrong, making it really hard to debug. Here, I've tried to reduce the problem to its most transparent form (multiplying 1 by 1 must equal 1, not 0.013......

In element-wise operations, position matters. Values that correspond positionally are combined to create a new value. To add to and/or subtract matrices or vectors: And in Python: vector_one = np.array([[1,2],[3,4]]) vector_two = np.array([[5,6],[7,8]]) ...
StdMat: where a full-rank matrix of the operator on a standard element is constructed, so that the operator can be evaluated with a single matrix-matrix multiplication; • IterPerExp: where the sum-factorisation technique is evaluated using an iteration over each element, but geometric factors...
The time discrete energy rates are obtained by vector multiplication of Systems (134) and (137) by and respectively. This computation provides the implicit midpoint discretization of Proposition 6, Proposition 7.□ The algebraic systems (134) and (137) satisfy a time discrete power balance, toget...
The NumPy multiply() function can be used to compute the element-wise multiplication of two arrays with the same shape, as well as multiply an array with
