Reinforcement Learning and Deep RL Python Theory and Projects - Solution (Alpha)

The video tutorial explores the impact of learning rate values on the convergence of Q-learning algorithms. It explains that a learning rate of zero results in no learning, as the new value remains the same as the old value. Conversely, a learning rate of one leads to instability, as the algorithm constantly updates with new values, neglecting the old ones. The optimal learning rate should be between zero and one, depending on the desired speed and stability of learning. A dynamic learning rate, which starts high and gradually decreases, can be used to balance the importance of new and old values over time.

Discuss the relationship between learning rate and the stability of the Q-learning algorithm.
