Fixes for this include experience replay and using a frozen copy of the q ^ network to calculate the TD target. For Q learning, maximisation bias is a problem, whereby the action chosen is more likely to have an over-estimate of its true value. This can be fixed by double 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 ... WebSep 30, 2024 · Off-policy: Q-learning. Example: Cliff Walking. Sarsa Model. Q-Learning Model. Cliffwalking Maps. Learning Curves.
