Speaker: Jun Dai Title: An Introduction to Time Series Analysis and Prediction Abstract: This talk introduces the theory and method of Time Series analysis, and applies it to solve the server load prediction problem. High bandwidth and energy cost has become increasingly important in network service systems. How to cut down the energy cost and bandwidth budget is one of the top concerns nowadays. Time Series Analysis can be used to solve such problem. By modeling and forecasting based on time series, network traffic bandwidth requirement and server workload can be predicted so as to provide managers more information for further actions to save energy cost and bandwidth.
