Since we are talking operators, there's also @ operator for matrix multiplication (don't worry, this time it's for real). >>> import numpy as np >>> np.array([2, 2, 2]) @ np.array([7, 8, 8]) 46 💡 Explanation:
reshape(2, 6) print("matrix:", matrix, matrix.shape, matrix.ndim) tensor = np.arange(12).reshape(2, 3, 2) print("tensor:", tensor, tensor.shape, tensor.ndim) 2向量 向量的两种定义: 从代数角度看,先对两个数字序列中的每组对应元素求积,再对所有积求和,结果即为点积。 从几何角度看,点积...
The fundamental difference between this example and the short snippet from last section is that for each utterance we are reading the raw audio data from disk and computing two feature matrices on the fly instead of reading a single precomputed feature matrix from disk.

>> arr_1 = [1,2,3]; >> arr_2 = [4,5,6]; >> arr_1 * arr_2 Error using * Incorrect dimensions for matrix multiplication. Check that the number of columns in the first matrix matches the number of rows in the second matrix. To perform elementwise multiplication, use '.*'.In...

This is exactly the way we would index elements of a matrix in linear algebra. 这正是我们在线性代数中索引矩阵元素的方法。 We can also slice NumPy arrays. 我们还可以切片NumPy数组。 Remember the indexing logic. 记住索引逻辑。 Start index is included but stop index is not,meaning that Python ...

In addition to sequence operations and list methods, Python includes a more advanced operation known as a list comprehension expression, which turns out to be a powerful way to process structures like our matrix. Suppose, for instance, that we need to extract the second column of our sample ma...
