Abstract
A context-aware service in a smart environment aims to supply services according to user situational information, which changes dynamically. Most exist- ing context-aware systems provide context-aware services based on supervised algorithms. Reinforcement algorithms are another type of machine-learning algo- rithm that have been shown to be useful in dynamic environments through trial- and-error interactions. They also have the ability to build excellent self-adaptive systems. In this study, we aim to incorporate reinforcement algorithms (Q-learn- ing) into a context-aware system to provide relevant services based on a user’s dynamic context. To accelerate the convergence of reinforcement learning (RL) algorithms and provide the correct services in real situations, we propose a com- bination of the Q-learning and case-based reasoning (CBR) algorithms. We then analyze how the incorporation of CBR enables Q-learning to become more effi- cient and adapt to changing environments by continuously producing suitable ser- vices. Simulation results demonstrate the effectiveness of the proposed approach compared to the traditional CBR approach.
