摘要:In this presentation, we will show some research results on optimal resource control in cloud computing and big data analytics by using Semi Markov Decision Process (SMDP) and machine learning methodology. SMDP is a mathematical framework that can model decision-making in situations where outcomes are partly random and partly under the control of the decision maker in continuous time. For the cloud computing and big data study, due to the large volume of data to process upon a limited computing resources, there are many challenges to achieve an optimal usage of the system resources. For example, the data is in general distributed to many servers for parallel processing, but how to optimally and efficiently distribute the data to meet the various demand is always a challenge. In this presentation, we will provide a case study with SMDP on incoming data control in the big data services. The requests are in different classes with different priorities, the requests with higher priorities are served with faster responses. We show how to model and then solve the SMDP model with some fixed decision rules which would help us in the design of the entire system. To further expand the study, machine learning techniques can be used to derive the probability distribution of the incoming data. By studying the properties of different probability distributions, we will be able to derive an optimal policy to achieve the best performance of the big data system.

报告人简介Wenlong Ni received the B.Sc. degree from Tsinghua University, China, in 1999, the M.Sc. degree from Kobe University, Japan, in 2003, and Ph.D. from the University of Toledo, USA, in 2008. After receiving Ph.D., he worked as a Research engineer in several companies including top 500 company Microsoft and Sinopec and also as a Postdoctoral research fellow in US. He had over ten years of industrial experience with computer technology like high performance computation, big data analysis and processing. During that period, Dr. Ni has made several recognized research contributions in complex wireless networks  through practical projects and publications such as in IEEE Transactions, Globecom, ICC and WCNC and others. In 2018, he started his new position in Jiang-Xi Normal University as an "oversea elite" professor in the department of computer information engineering and a candidate for "thousand youth" plan. His current research interests include performance evaluation, decision analysis and the applications in cloud computing, big data analytics, ads recommendation system, communications networks.
