It creates a pressing need for efficient and safe assistive devices, particularly in light of heightened demand due to war-related injuries. While cost has been a barrier to accessibility, techno-logical progress can democratize these solutions. Safety remains a paramount con-cern, especially given the intricate interactions between assistive robots and humans. This study explores the application of reinforcement learning (RL) and imitation learning in improving policy design for assistive robots. The proposed approach makes the risky policies safer without additional environmental interactions. The enhancement of the conventional RL approaches in tasks related to assistive robotics is demonstrated through experimentation using simulated environments.enassistive roboticsreinforcement learningdiffusion modelsimitation learningдопоміжна робототехніканавчання з підкріпленнямдифузійні моделіімітаційне навчанняReducing risk for assistive reinforcement learning policies with diffusion modelsЗниження ризиків стратегій навчання з підкріпленням для догляду із дифузійними моделямиArticleС. 148-154https://doi.org/10.20535/SRIT.2308-8893.2024.3.09004.8520000-0002-8265-642X
