Piecewise Stationary Modeling of Random Processes Over Graphs With an Application to Traffic Prediction
Arman Hasanzadeh, Xi Liu, Nick Duffield +1
Stationarity is a key assumption in many statistical models for random processes. With recent developments in the field of graph signal processing, the conventional notion of wide-…

Delay-Optimal Scheduling for Queueing Systems with Switching Overhead
Ping-Chun Hsieh, I-Hong Hou, Xi Liu
We study the scheduling polices for asymptotically optimal delay in queueing systems with switching overhead. Such systems consist of a single server that serves multiple queues, a…
