WebJan 9, 2024 · Learning from actual experience is striking because it requires no prior knowledge of the environment’s dynamics, yet can still attain optimal behavior. We will cover intuitively simple but powerful Monte Carlo methods, and temporal difference learning methods including Q-learning. WebAlgorithms that don't learn the state-transition probability function are called model-free. One of the main problems with model-based algorithms is that there are often many states, and a naïve model is quadratic in the number of states. That imposes a huge data requirement. Q-learning is model-free. It does not learn a state-transition ...
