How Does Q Learning simply explained | SARSA and Q-Learning Explanation Work?

Q Learning is like teaching a kid how to pick the best path through a maze by trying different ways and remembering what works.

Imagine you're playing a game where you move around a grid, like a big chocolate bar, and you want to get from one corner to another. Every time you take a step, you see if it leads you closer or farther from your goal. Q Learning is like having a map in your head that gets better every time you play, it helps you remember which moves are good so you can choose the best path next time.

How It Works

Q Learning learns by looking at what happens after each move, not just what's right in front of you. Think of it like this: if you're choosing between two paths, and one leads to a treat (like candy!), Q Learning helps you remember that choice so you can pick the same path again next time.

SARSA vs. Q-Learning

SARSA is like learning with a friend, you both try different paths and help each other learn what works best. Q Learning is more like learning alone, remembering your own choices to get better at the game by yourself.

Both are fun ways to get smarter at playing games, or solving real-life problems!
