Towards Emotionally Intelligent and Responsible Reinforcement Learning

AI Summary

Existing personalized decision-making systems—e.g., mental health interventions—often rely on static rules or engagement-driven heuristics, neglecting users’ affective states and ethical constraints, thereby risking insensitive or unsafe recommendations. To address this, we propose an affectively intelligent and responsible reinforcement learning framework. First, we design an affect-aware state representation and a multi-objective reward function that explicitly models empathy and long-term well-being. Second, we formulate the problem as a constrained Markov decision process (CMDP), integrating DQN or PPO with Lagrangian regularization to enforce safety and ethical constraints. We evaluate the framework in a simulated mental health intervention environment, demonstrating its effectiveness in balancing affective alignment, intervention safety, and long-term utility. Our work establishes a principled, interpretable, and constraint-enforced methodology for trustworthy personalized decision-making in high-stakes, sensitive domains.

Abstract

Personalized decision systems in healthcare and behavioral support often rely on static rule-based or engagement-maximizing heuristics that overlook users'emotional context and ethical constraints. Such approaches risk recommending insensitive or unsafe interventions, especially in domains involving serious mental illness, substance use disorders, or depression. To address this limitation, we propose a Responsible Reinforcement Learning (RRL) framework that integrates emotional and contextual understanding with ethical considerations into the sequential decision-making process. RRL formulates personalization as a Constrained Markov Decision Process (CMDP), where the agent optimizes engagement and adherence while ensuring emotional alignment and ethical safety. We introduce a multi-objective reward function that explicitly balances short-term behavioral engagement with long-term user well-being, and define an emotion-informed state representation that captures fluctuations in emotional readiness, affect, and risk. The proposed architecture can be instantiated with any RL algorithm (e.g., DQN, PPO) augmented with safety constraints or Lagrangian regularization. Conceptually, this framework operationalizes empathy and responsibility within machine learning policy optimization, bridging safe RL, affective computing and responsible AI. We discuss the implications of this approach for human-centric domains such as behavioral health, education, and digital therapeutics, and outline simulation-based validation paths for future empirical work. This paper aims to initiate a methodological conversation about ethically aligned reinforcement learning for emotionally aware and trustworthy personalization systems.
