element-wise multiply作用"Element-wise multiply"是一种针对两个向量或矩阵的操作,它将两个向量或矩阵中对应位置的元素相乘,生成一个新的向量或矩阵。 具体来说,如果有两个相同维度的向量或矩阵A和B,它们的element-wise multiply结果是一个新的向量或矩阵C,其中C的每个元素都等于A和B对应位置元素的乘积。 例如,...

a=np.array([1,2,3,4,5])b=np.array([2,3,4,5,6])result=np.multiply(a,b)print(result) 1. 2. 3. 4. 5. 6. 7. 该代码中,我们使用NumPy库中的multiply函数对两个NumPy数组a和b进行逐元素乘法计算。最终结果存储在result数组中。
We can also perform the element-wise multiplication of specific rows, columns, or submatrices of the matrices using thenp.multiply()method. We need to pass the specific rows, columns, or submatrices of the matrices to thenp.multiply()method. Like in the element-wise matrix multiplication, the...

Elementwise 操作,即逐元素操作,是指对 Tensor 中的每个元素应用一个函数变换,得到最终输出结果。在深度学习里,有很多算子属于 Elementwise 算子范畴,比如常用的激活函数(如ReLU、GELU、Sigmoid)、ScalarMultiply(对 Tensor 每个元素都乘上一个标量)等操作。
