在中兴、中国移动和腾讯等知名企业的支持下，为解决无线网络下大规模视频及VR/AR视频传输的难题，本课题组首创从基于弱监督学习的无线网络模态分类问题出发，把握复杂多变的无线网络的内在特征；结合前沿的云计算-边缘计算协同技术和自适应码率传输技术，从多维资源优化方法及深度增强学习两个方向展开深入研究，有效提升了在有限网络条件下观看视频的用户体验质量。在设备方面，课题组提供高性能GPU服务器，实验网络，VR头戴式显示器及GoPro全景摄像头等。

• 面向物联网的分布式/边缘协同计算

随着物联网时代到来以及终端数据量的指数级增加，数据中心算力逐渐不足以支撑海量数据处理任务。在多项国家级项目的支持下，课题组提出边缘侧多节点集群，结合计算虚拟化技术，构建分布式计算系统，结合凸优化理论及深度增强学习方法展开任务卸载和调度算法研究，以缓和云端计算压力并提升用户服务体验。设备方面，课题组提供高性能服务器从而支持单节点多容器集群实验，同时也提供多个典型边缘计算节点以组成真实的多节点分布式计算集群，以验证算法有效性和k8s、docker等技术在相应场景下的合理性。

• AI数字人及其行业应用

在国家级项目和高新企业的支持下，课题组研究AI数字人，即细分领域（如生活服务、医疗、教育、娱乐）的开放式对话交互系统，最终以数字（赛博）空间中具备人类情感的虚拟人物形象出现。课题组聚焦前沿的深度学习、Transformer、大规模预训练等技术。对话交互系统包括个性化生成模块、情感分析模块、主题提取模块、记忆提取模块、知识库检索推荐模块以及话题引导模块等。
