Questions & Answers

Q: What is the purpose of using Open AI Gym in this tutorial?

Open AI Gym provides a way to model tasks and create environments for training neural networks. In this tutorial, we use the cart pole environment to train an agent to balance the pole.

Q: How is the score calculated in the cart pole environment?

In the cart pole environment, the score increases by one for each frame that the pole remains balanced. The goal is to achieve a score of 200 or greater, which is considered solved.

Q: What is the role of random moves in the training process?

Initially, random moves are made by the agent to gather starting data. These random moves will be used to train the neural network.

Q: What role does the neural network play in this tutorial?

The neural network is used to train the agent by predicting the next move based on the input from the environment. It learns from the random moves initially made and tries to improve the score in subsequent training iterations.

Summary & Key Takeaways

• Neural networks require large amounts of data, but if the task can be modeled, data sets can be generated to train the network.

• Open AI Gym provides a variety of environments for modeling tasks, including the cart pole environment used in this tutorial.

• The goal of the tutorial is to train an agent to balance the pole by moving the cart, with a score of 200 or greater considered as solved.
