Description: Value Iteration is a fundamental algorithm in the realm of Markov Decision Processes (MDPs), used to compute the optimal policy and the value function associated with a state. This method is based on the idea that the value function of a state can be iteratively improved, using information from expected rewards and transitions between states. In each iteration, the current value function is evaluated and updated based on possible actions and their respective rewards, until convergence is reached, meaning that changes in the value function are minimal. Value Iteration is particularly relevant in reinforcement learning, where the goal is to maximize accumulated rewards over time. This approach allows agents to learn to make optimal decisions in uncertain and dynamic environments, making it a powerful tool in artificial intelligence and machine learning. Its implementation in various libraries facilitates the creation of models that can handle sequences of data, thus enabling the resolution of complex problems across various applications, from robotics to natural language processing.
