(1) A replaces one vector, and B replaces two vectors.
When the data dimension is large, A has half the computing time and computational complexity as that of B.
(2) A represents only the probability related to data C, but B in D expresses the probability of C, the values calculated by the method of E, etc.
(3) Because the position of C in A has not been replaced, it is easy to monitor, change and necessarily adjust C during calculation. |
