Reinforcement Learning and Deep RL Python Theory and Projects - Gamma and Discount Factor

The video tutorial introduces the concept of gamma, a discount factor in reinforcement learning, explaining its role in penalizing later steps in decision-making processes. The instructor uses examples to illustrate the importance of initial steps and how gamma affects the significance of subsequent actions. The tutorial also covers the application of gamma in code and its impact on Q table updates. The session concludes with a brief introduction to the next topic, alpha, the learning rate.
