A reinforcement learning approach for training complex decision making models.

摘要

Reinforcement learning (RL) is a potent and significant machine learning branch that allows the systems to discover the best strategies through trial-and-error interactions with their environments, thereby making it a logical culprit for handling complex decision-making problems. Unlike traditional methods, which depend on a set of already defined rules or labeled datasets, RL rewards the models for the behavior that is desired and thus they train by themselves and further adjust to the environment by changing dynamically. Due to this feature to self-learn and thus better performance, RL is becoming more and more important in various application areas, such as robotics, video games, the financial sector, and the medical field, where intelligent systems are required to take very subtle decisions in totally different manners. The article talks about the main ideas of reinforcement learning and thus discusses how agents learn by combining exploration and exploitation. We are also introducing various popular algorithms such as Q-learning, Deep Q-Networks, and Policy Gradient methods along with their real-world usage. One of the important factors in this paper is that we present the examples related to the supply chain to show the RL revolutionary potential to train the system to solve complex decision-making problems. But the real-world scenario of RL is faced with several problems happening simultaneously, such as sample inefficiency, reward shaping, and scaling of complex solutions, just to name a few. We also suggest practical solutions to the problem, for instance, using hybrid methods, increasing the precision of the simulation of the environment, and designing perfect reward structures. Besides this, we are also talking about the importance of a combination of RL with other techniques like supervised learning and evolutionary algorithms to get better results
