Introduction: The Importance of Markov Decision Processes (MDP)
The importance of topics related to Artificial Intelligence and Reinforcement Learning is increasing in the Information Management Professional Engineer exam. Among these, the Markov Decision Process (MDP) provides a core theoretical foundation and can be applied to solve various problems. This post covers everything from the basic concepts of MDP to in-depth content for preparing for the Information Management Professional Engineer exam. The goal is to provide students preparing for the 2026 exam with a clear understanding of MDP and effective learning strategies.
Core Concepts and Principles
A Markov Decision Process is a mathematical framework for modeling sequential decision-making. MDP consists of State (S), Action (A), Reward (R), and state transition probabilities. An agent selects an action in a specific state, transitions to another state as a result, and receives a reward in the process. The goal is to find the optimal policy that maximizes cumulative rewards.
Components of MDP
- State (S): Represents the current situation of the system.
- Action (A): A set of actions that an agent can take in a specific state.
- Reward (R): The immediate reward an agent receives as a result of taking an action.
- Transition Probability (P): The probability of transitioning to another state when taking an action in a specific state.
- Policy (π): A rule that defines which action to choose in each state.
Latest Trends and Changes
Recently, Deep Reinforcement Learning, which combines Deep Learning and MDP, has been gaining attention. Deep Reinforcement Learning enables effective decision-making in problems with complex state spaces and action spaces. In addition, various studies are underway to increase the applicability in real-world environments. New algorithms and frameworks related to MDP are expected to emerge in 2026.
Practical Application Methods
MDP can be used in various fields. For example, it can be used to make optimal decisions in robot control, game AI, resource management, and financial transactions. In particular, in the field of information management, MDP can be applied to system operation, network management, and security policy decisions to improve efficiency. In practice, it is necessary to design an MDP model and collect data to train the model.
Expert Advice
💡 Technical Insight
Precautions When Introducing Technology: When designing an MDP model, it is important to accurately identify the characteristics of the problem and define appropriate states, actions, and rewards. It is also important to reduce the complexity of the model and secure sufficient training data.
Outlook for the Next 3-5 Years: MDP is expected to be used in more diverse fields with the development of artificial intelligence technology. In particular, it will become a core technology for data-driven decision-making systems. The proportion of MDP-related questions is expected to increase in the Information Management Professional Engineer exam.
