Prof. Guo was an IEEE ComSoc Distinguished Lecturer (2017-2018) and served in IEEE ComSoc Board of Governors (2018-2019). He has also served as General and Program Chair for numerous IEEE conferences. Prof. Guo is an IEEE Fellow, the Editor-in-Chief of IEEE Open Journal of the Computer Society, and Associate Editor of IEEE Transactions on Cloud Computing, IEEE Transactions on Sustainable Computing, and IEEE Transactions on Green Communications and Networking.
When accessing cloud-hosted modern applications, users often suffer a significant latency due to the long geo-distance to the central cloud. Edge computing thus emerges as an alternative paradigm that can reduce this latency by deploying services close to users. In this talk, we will analyze the methodology and limitations of popular approaches for supporting AI services on geo-distributed systems along the evolution from cloud computing to edge computing. In particular, we shall discuss how to deal with different sets of challenges in distributed machine learning over heterogeneous geo-distributed systems. We shall also present our recent studies on parameter-server based framework among networked collaborative edges.
