To make mHealth apps more effective and engaging, personalization has emerged as a key approach. One promising method to achieve personalization is reinforcement learning (RL), a machine learning method well-suited for sequential decision-making. In this study, we introduce and apply an offline RL framework adapted to the novel setting of mHealth personalization. This framework includes algorithms that leverage historical user data and there is an emphasis on explainable AI to ensure interpretability. By using an offline approach, the framework enables the application of RL without the costs or risks associated with real-world experiments.

摘要

To make mHealth apps more effective and engaging, personalization has emerged as a key approach. One promising method to achieve personalization is reinforcement learning (RL), a machine learning method well-suited for sequential decision-making. In this study, we introduce and apply an offline RL framework adapted to the novel setting of mHealth personalization. This framework includes algorithms that leverage historical user data and there is an emphasis on explainable AI to ensure interpretability. By using an offline approach, the framework enables the application of RL without the costs or risks associated with real-world experiments.
