In it you will learn the basics of Reinforcement Learning, one of the three paradigms of modern artificial intelligence. You will implement from scratch adaptive algorithms that solve control tasks based on … WebbQ-Learning vs. SARSA. Two fundamental RL algorithms, both remarkably useful, even today. One of the primary reasons for their popularity is that they are simple, because by default they only work with discrete state and action spaces. Of course it is possible to improve them to work with continuous state/action spaces, but consider discretizing ...
Webb15 apr. 2024 · Gathering Data. Gathering the necessary data is a crucial step when training a reinforcement learning model. Training data should be representative of the goals that you want to achieve, and it must be balanced — not biased in any particular direction. Make sure to provide sufficient variety in terms of input/output pairs as well as different ... Webb16 feb. 2024 · Performance difference. Q-learning directly learns the optimal policy because it maximises the reward with a greedy action selection strategy. This removes the chance that the agent uses an exploration step from the second step in de update function. SARSA can use an exploration step in the second step, because it keeps following the ε …
Webb23 jan. 2024 · Both Q-learning and SARSA will lead our agent to the goal, but there are some difference we have to take into account. As I said previously, SARSA is more conservative than Q-learning: thus it will prefer a “longer” path towards the goal (therefore also getting less reward) but safer (it will try to keep distance from what cause the …
