Q-greedyUCB: a New Exploration Policy for Adaptive and Resource-efficient Scheduling
Yu Zhao, Joohyun Lee, Wei Chen
This paper proposes a learning algorithm to find a scheduling policy that achieves an optimal delay-power trade-off in communication systems. Reinforcement learning (RL) is used to…
Delay-Optimal and Energy-Efficient Communications with Markovian Arrivals
Xiaoyu Zhao, Wei Chen, Joohyun Lee +1
In this paper, delay-optimal and energy-efficient communication is studied for a single link under Markov random arrivals. We present the optimal tradeoff between delay and power o…
A Faster FPTAS for Knapsack Problem With Cardinality Constraint
Wenxin Li, Joohyun Lee
We study the -item knapsack problem (i.e., -dimensional KP), which is a generalization of the famous 0-1 knapsack problem (i.e., -dimensional KP) in which an upper bound…
A Change-Detection based Framework for Piecewise-stationary Multi-Armed Bandit Problem
Fang Liu, Joohyun Lee, Ness Shroff
The multi-armed bandit problem has been extensively studied under the stationary assumption. However in reality, this assumption often does not hold because the distributions of re…
Delay-Optimal Probabilistic Scheduling with Arbitrary Arrival and Adaptive Transmission
Xiang Chen, Wei Chen, Joohyun Lee +1
In this paper, we aim to obtain the optimal delay-power tradeoff and the corresponding optimal scheduling policy for an arbitrary i.i.d. arrival process and adaptive transmissions.…
Delay-Optimal Buffer-Aware Scheduling with Adaptive Transmission
Xiang Chen, Wei Chen, Joohyun Lee +1
In this work, we aim to obtain the optimal tradeoff between the average delay and the average power consumption in a communication system. In our system, the arrivals occur at each…
