The value function V(s) quantifies the usefulness or goodness of being in state s and the advantage function A(a) quantifies the advantage of action a over other possible actions. Therefore,

Dueling DQN has separate networks to compute the value and advantage functions and then combine them back to fetch the value for the Q-function. The reason behind decoupling the computation of value and advantage is that the agent doesn't have to take care of the unnecessary value function computations ...
