Multi Agent vs Single Agent Deep Reinforcement Learning
Watch: Introduction to Multi-Agent Reinforcement Learning by MATLAB Deep Reinforcement Learning (DRL) has transform AI by enabling systems to learn complex decision-making processes through trial and error. However, the distinction between single-agent and multi-agent frameworks determines how these systems tackle challenges ranging from robotics to autonomous vehicles. Understanding their unique strengths and applications is critical for industries using AI to solve real-world problems.. Single-agent DRL focuses on optimizing the decisions of one autonomous entity. This approach excels in scenarios where a single system must manage a dynamic environment with predefined goals, such as game-playing AI (e.g., AlphaGo) or robotic arm control. As mentioned in the Introduction to Single Agent Deep Reinforcement Learning section, these systems operate in environments where inter-agent interaction is minimal or unnecessary. For example, a study on robotic shaft-hole assembly demonstrated that single-agent DDPG (Deep Deterministic Policy Gradient) struggles to converge in tasks requiring precise orientation control. However, it remains a strong baseline for problems where coordination between agents isn’t necessary.
