## Q&A

What is reinforcement learning?

Reinforcement learning is a branch of machine learning that enables programs to learn by interacting with an environment and receiving rewards or penalties for their actions.

Can I implement reinforcement learning without a strong mathematical background?

Yes, this video presents a simple method to implement reinforcement learning that requires less theoretical knowledge. It allows for hands-on learning and building intuition about the fundamental principles.

How do neural networks evolve in reinforcement learning?

Neural networks in reinforcement learning evolve their architecture and weights as training progresses. This allows them to adapt and improve their performance in solving complex tasks.

What are directed acyclic graphs (DAGs) in reinforcement learning?

Directed acyclic graphs (DAGs) are used to represent neural networks in reinforcement learning. They consist of three types of nodes: inputs, hidden nodes, and outputs, which together form the structure of the network.

What does the training process in reinforcement learning involve?

The training process in reinforcement learning consists of iterations of evaluation, selection, and mutation. The network performance is evaluated, the best performers are selected for the next iteration, and random mutations are introduced to explore new solutions.
