AI总结:

本文提出基于博弈论的社区感知观点形成过程(GCAOFP),将社区形成建模为非合作博弈,并在有界置信度下更新观点,理论证明该共同演化过程必在有限迭代后达到均衡,且观点收敛仅发生在社区内部。

摘要:

考察由众多个体组成的现实社会系统中观点形成与演化的内在机制,可以为有效的社会运转和明智的商业决策提供有价值的洞见。我们研究的重点在于网络化多智能体系统内部的观点动力学。我们提出了一种新颖的方法,称为基于博弈论的社区感知观点形成过程(GCAOFP),以准确刻画现实社会系统中社区与观点的共同演化动力学。GCAOFP算法在每次迭代中包含两个不同的步骤。1)社区动力学过程将社区形成过程概念化为一个涉及有限数量智能体的非合作博弈。每个个体智能体通过采取能够带来最有利社区标签更新的响应来最大化自身效用。2)观点形成过程涉及在包含有界置信度的社区感知框架内更新个体智能体的观点。该过程考虑了更新后的社区成员矩阵,并确保智能体的观点在特定限制范围内与其所在社区内其他智能体的观点保持一致。本研究提供了理论证明:在任何初始条件下,上述共同演化动力学过程最终都将达到均衡状态。在该状态下,观点向量和社区成员矩阵都将在有限次迭代后趋于稳定。与传统的观点动力学模型相比,同一社区内智能体观点的保证收敛确保了观点收敛仅发生在给定社区内部。

英文摘要:

Examining the mechanisms underlying the formation and evolution of opinions within real-world social systems, which consist of numerous individuals, can provide valuable insights for effective social functioning and informed business decision making. The focus of our study is on the dynamics of opinions inside a networked multi-agent system. We provide a novel approach called the Game Theory Based Community-Aware Opinion Formation Process (GCAOFP) to accurately represent the co-evolutionary dynamics of communities and opinions in real-world social systems. The GCAOFP algorithm comprises two distinct steps in each iteration. 1) The Community Dynamics Process conceptualizes the process of community formation as a non-cooperative game involving a finite number of agents. Each individual agent aims to maximize their own utility by adopting a response that leads to the most favorable update of the community label. 2) The Opinion Formation Process involves the updating of an individual agent's opinion within a community-aware framework that incorporates bounded confidence. This process takes into account the updated matrix of community members and ensures that an agent's opinion aligns with the opinions of others within their community, within certain defined limits. The present study provides a theoretical proof that under any initial conditions, the aforementioned co-evolutionary dynamics process will ultimately reach an equilibrium state. In this state, both the opinion vector and community member matrix will stabilize after a finite number of iterations. In contrast to conventional opinion dynamics models, the guaranteed convergence of agent opinion within the same community ensures that the convergence of opinions takes place exclusively inside a given community.
