Np.dot和np.multiply
Having looked around it seems as though numpydot should be used for faster array multiplication with respect to as long as BLAS is installed and working with numpy. - 在表示集合的符号中如nr的右上方有星号则表示正数如n表示正整数集合r表示正实数集合 只有电脑里才有星号一说电脑里的星号就是乘号的意思如27即是2x7.

Logprobs npdot Y nplog A2T npdot 10-Y nplog 1 - A2T print logprobsshape print logprobs cost -1m logprobs print. Npdot is the dot product between two vectors dot product mathematically is the value of the product of the two vectors multiplied by cosine the angle in between in a two dimensional coordinates it is equivalent to X1 X2 Y1 Y2 As a general form AB sum aibi so just use npmultiply. This is frequently recommended.
