Abstract:Negotiation refers to the process in which people communicate with each other on certain topics to reach an agreement. Automated negotiation aims to reduce negotiation costs, improve negotiation efficiency, and optimize negotiation results by using negotiating agents. In recent years, deep reinforcement learning techniques have been applied to the field of automated negotiation with good results. However, there are still problems such as the long training time of agents, dependence on specific negotiation domains, and insufficient utilization of negotiation information. Therefore, this study proposes a negotiation strategy based on the TD3 deep reinforcement learning algorithm, which reduces the exploration cost of the training process through pre-training and improves the robustness of the negotiation strategy by optimizing the state and action definitions, so as to adapt to different negotiation scenarios. In addition, it makes full use of the interaction information of the negotiation by multi-head semantic neural network and opponent preference prediction module. The experimental results show that the strategy can perform the negotiation task well in different negotiation environments.
