Recent years saw a surge of development of artificial intelligence (AI) algorithms for decision making. These increasingly sophisticated algorithms make use of the ever-growing stores of information to make increasingly high stakes decisions. With this shift comes a pressing need to ensure that the decisions of these algorithms are fair and equitable to all parties involved, and are directed toward the public greater good. There are many ways to interpret "fairness" and "public good". This proposal focuses on fairness notions from multiagent systems and game theory. Multiagent systems is the study of communities of agents each acting independently, often according to its own interests. Game theory is the mathematics of strategic decision-making in the presence of other strategic agents. Taken together, these fields provide a rich model of the physical and digital spaces in which AI algorithms operate. They also provide fairness notions that characterize how beneficial or equitable algorithms are - for instance, an algorithm may be "truthful" where agents have no incentives to provide false reports; or, the outcome may be at a "Nash equilibrium" where agents are reasonably satisfied that they would not want to alter their actions. We focus on a particular domain for the research and application of these fairness notions - social networks. On a societal level, social networks (in the form of social media platforms) touch many aspects of our lives. They gather vast amounts of information about us and use this information to drive AI algorithms that may or may not be acting in the interest of the public good. They also control the propagation of information in digital spaces, and therefore are in a position to mediate both useful messages as well as harmful disinformation. This proposal examines how we can best leverage AI algorithms in a social network environment toward the public good, toward achieving fair and equitable outcomes for all participants.

近年来，用于决策的人工智能（AI）算法的发展激增。这些日益复杂的算法利用不断增长的信息存储来做出越来越高的风险决策。随着这一转变，迫切需要确保这些算法的决策对所有相关方都是公平和公正的，并且是为了公众的更大利益。对“公平”和“公益”的解读有很多种。该提案侧重于多智能体系统和博弈论的公平概念。多智能体系统是对每个独立行动的智能体社区的研究，通常根据自己的利益。博弈论是在其他战略代理人存在的情况下进行战略决策的数学。总之，这些领域提供了人工智能算法运行的物理和数字空间的丰富模型。它们还提供了公平的概念，描述了算法的有益性或公平性-例如，算法可能是“真实的”，其中代理人没有提供虚假报告的动机;或者，结果可能是“纳什均衡”，其中代理人合理地满意他们不想改变他们的行为。 我们专注于这些公平概念的研究和应用的一个特定领域-社交网络。在社会层面上，社交网络（以社交媒体平台的形式）触及我们生活的许多方面。他们收集了大量关于我们的信息，并使用这些信息来驱动人工智能算法，这些算法可能会也可能不会为公共利益而采取行动。它们还控制着数字空间中的信息传播，因此能够调解有用的信息和有害的虚假信息。该提案探讨了我们如何在社交网络环境中最好地利用人工智能算法来实现公共利益，为所有参与者实现公平和公正的结果。
