A Fast-Pivoting Algorithm for Whittle’s Restless Bandit Index [PDF]

open access: yesMathematics, 2020
The Whittle index for restless bandits (two-action semi-Markov decision processes) provides an intuitively appealing optimal policy for controlling a single generic project that can be active (engaged) or passive (rested) at each decision epoch, and ...

On the Optimality of the Whittle’s Index Policy for Minimizing the Age of Information [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2021
In this paper, we consider the average age minimization problem where a central entity schedules M users among the N available users for transmission over unreliable channels. It is well-known that obtaining the optimal policy, in this case, is out of reach.

Tabular and Deep Learning for the Whittle Index

open access: yesACM Transactions on Modeling and Performance Evaluation of Computing Systems
The Whittle index policy is a heuristic that has shown remarkably good performance (with guaranteed asymptotic optimality) when applied to the class of problems known as Restless Multi-Armed Bandit Problems (RMABPs). In this article, we present QWI and QWINN, two reinforcement learning algorithms, respectively tabular and deep, to learn ...

A learning algorithm for the Whittle index policy for scheduling web crawlers [PDF]

open access: yes2019 57th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2019
We revisit the Whittle index policy for scheduling web crawlers for ephemeral content proposed in Avrachenkov and Borkar, IEEE Trans. Control of Network Systems 5(1), 2016, and develop a reinforcement learning scheme for it based on LSPE(0). The scheme leverages the known structural properties of the Whittle index policy.

Whittle index approach to opportunistic scheduling with partial channel information [PDF]

open access: yesPerformance Evaluation, 2019
Abstract Opportunistic scheduling in wireless cellular systems utilizes random channel quality variations in time by favoring the users with good channel conditions. However, the success of such schedulers is heavily depending on the accuracy of the available information on the channel states of users.

A Whittle's Index Based Approach for QoE Optimization in Wireless Networks [PDF]

open access: yesProceedings of the ACM on Measurement and Analysis of Computing Systems, 2018
The design of schedulers to optimize heterogeneous users' Quality of Experience (QoE) remains a challenging and important problem for wireless systems. This paper explores three inter-related aspects of this problem: 1) non-linear relationships between a user's QoE and flow delays; 2) managing load dependent QoE trade-offs among heterogeneous ...
