What is Reward Functions
Beginner
A reward function defines the score or feedback signal that a reinforcement learning agent receives after taking an action, guiding it toward desired behavior.
Real-world example
A self driving car simulation might use a reward function that gives points for staying in lane and penalties for collisions.
