Reinforcement Learning (RL) has emerged as a crucial component in the field of Machine Learning, enabling systems to learn optimal behaviors through interaction with their environment. At the heart of this process are reward functions, which play a pivotal role in shaping the learning experience of an RL agent. This blog post delves into the significance of reward functions in reinforcement learning and how they influence the development of effective RL systems. Understanding Reward Functions In reinforcement learning, an agent learns to make decisions by receiving feedback from the environment in the form of rewards. A reward function is essentially a mathematical tool that quantifies the benefit of a particular action or sequence of actions. It provides the agent with a signal that guides its learning process, helping it to evaluate the desirability of its actions. The reward function serves as a map between the agent’s actions and the corresponding rewards it receives. It is crucial...
