成电讲堂

　　4月21日下午，由人力资源部教师发展中心主办、信息与通信工程学院承办的“名师讲堂”邀请到IEEE Fellow、南洋理工大学教授Dusit Niyato，作主题为“Metaverse Virtual Service Management: Game Theoretic Approaches”的线上精彩报告。本次学术交流活动由信息与通信工程学院胡杰研究员主持。

　　Dusit Niyato教授主要讲解了在无线边缘授权的元宇宙中的虚拟现实（VR）用户可以通过不同供应商提供的VR服务沉浸在虚拟世界中。VR服务提供商（SP）由于其有限的通信和计算资源，必须高效、经济地优化VR服务。因此激励机制可以作为供应商和用户之间管理VR服务的有效工具。其团队在元宇宙中提出了一个基于学习的VR服务激励机制框架。其次，考虑通过数字孪生（DT）提供的虚拟服务，即元宇宙中真实世界实体的数字复制。Dusit Niyato教授指出，物联网设备和传感器收集的真实世界数据是同步这两个世界的关键。元宇宙平台使用一组物联网设备代表虚拟服务提供商（VSPs）收集此类数据。设备所有者出于自身利益，会动态选择一VSP以最大化奖励。采用混合进化动力学，其中异构设备所有者群体可以使用不同的修订协议来更新他们的策略。他和师生们讨论了元宇宙虚拟服务管理的一些重要研究方向。

　　 在交流环节中，Dusit Niyato教授与师生进行了交流讨论，师生们踊跃提问，收获颇丰。
