theoretical derivation

基本解释

By a theoretical derivation of BP and RM algorithms, the algorithms are the same on principle.
通过对BP算法和RM算法的理论推导，从原理上说明了两种算法的一致性。
This found that if the reverse idea of the electron charge-mass ratio as a known quantity, it can re-theoretical derivation, and thus obtain the value of the vacuum in the speed of light.
笔者发现，如果进行逆向构思，把电子的荷质比作为已知量时，可重新进行理论推导从而得到真空中的光速值。
In this paper, the flux of the transformer is obtained by theoretical derivation, then models of transformer and CT are built for simulation, and an experiment is done to prove the results.
该文首先对变压器磁链进行理论推导，然后建立变压器和CT模型进行仿真，并通过实验验证结果。
