A Whittle Index Approach to Minimizing Age of Multi-Packet Information in IoT Network
IEEE Access, 2021 Age of information (AoI) captures the freshness of information and has been used broadly as an important performance metric in big data analytics in the Internet of Things (IoT).

Whittle Index Policy for Crawling Ephemeral Content [PDF]
IEEE Transactions on Control of Network Systems, 2015 We consider a task of scheduling a crawler to retrieve content from several sites with ephemeral content. A user typically loses interest in ephemeral content, like news or posts at social network groups, after several days or hours. Thus, development of timely crawling policy for such ephemeral information sources is very important. We first formulate

Long range dependency and forecasting of housing price index and mortgage market rate: evidence of subprime crisis [PDF]
Management Science Letters, 2015 In this paper, we examine and forecast the House Price Index (HPI) and mortgage market rate in terms of the description of the subprime crisis. We use a semi-parametric local polynomial Whittle estimator proposed by Shimotsu et al. (2005) [Shimotsu, K., &

ACM SIGMETRICS Performance Evaluation Review, 2022 The Whittle index policy is a heuristic that has shown remarkable good performance (with guaranted asymptotic optimality) when applied to the class of problems known as multi-armed restless bandits. In this paper we develop QWI, an algorithm based on Q-learning in order to learn theWhittle indices. The key feature is the deployment of two timescales, a

Whittle Index Approach to Energy-Aware Dispatching [PDF]
2018 30th International Teletraffic Congress (ITC 30), 2018 A data center can be modeled as a set of parallel queues, and the dispatcher decides to which queue the arriving jobs are routed. We consider an energy-aware dispatching system in a Markovian setting, where each server upon becoming empty enters a sleep mode to save energy and to activate the server after sleep incurs an additional setup delay cost. We

Markovian Restless Bandits and Index Policies: A Review
Mathematics, 2023 The restless multi-armed bandit problem is a paradigmatic modeling framework for optimal dynamic priority allocation in stochastic models of wide-ranging applications that has been widely investigated and applied since its inception in a seminal paper by
