| Abstract |
Developing chatbot system is a challenging problem in artificial intelligence and many people recently begin to use deep reinforcement learning in this area. In addition, policy network method has been widely used in deep reinforcement learning for chatbot. In this paper, we propose a new method of dual policy network for dialog generation in deep reinforcement learning. In dual policy network, one policy network is dedicated to a dialog policy for a specific person while the other is for other persons. The proposed model was tested using real dialog dataset and could generate more user-specific dialogue. |
