ELI5: How do AI agents work

AI agents are like smart helpers that learn from experience to do things for you.

Imagine you have a robot dog, that's like an AI agent. At first, the robot dog doesn't know how to fetch. But you can teach it!

Here's how it learns, just like an AI agent:

• You show it what "fetch" means: You throw a ball and say "Fetch!".
• It tries to do what you want: Maybe it barks, maybe it runs around randomly.
• You give it feedback: If it brings the ball back, you say "Good dog!" (a reward). If it doesn't, you say "No, fetch!" (a penalty).
• It learns from the feedback: After many tries, the robot dog learns that bringing the ball equals "Good dog!" and becomes good at fetching.

• They have a goal: Like finding the best route on Google Maps, or suggesting a movie you'll like on Netflix.
• They try different things: They might try different routes, or different movie suggestions.
• They get feedback: Based on traffic data or whether you liked the movie, they learn what works and what doesn't. This feedback is often called data.
• They get better over time: The more they try and the more data they get, the better they become at achieving their goal.
