Reinforcement learning (RL) offers a promising alternative by enabling personalized, real-time insulin adjustments that improve the balance between hyperglycemia and hypoglycemia.<h4>Objective</h4>This study aims to develop a deep Q-network (DQN)-based RL system that dynamically personalizes insulin dosing recommendations using continuous glucose monitoring data, meal intake, and physical activity levels. The gene discussed is INS; the disease is Hyperglycemia.
