RLHF stands for Reinforcement Learning from Human Feedback, it’s like teaching a robot to learn by getting advice from people.
Imagine you're learning to ride a bike, and every time you wobble or fall, your friend gives you a tip. Over time, with enough tips, you get better at riding. That's kind of how RLHF works!
How It Works
At first, the robot (or AI) doesn’t know what it’s doing, it just tries random things. Then people come in and say, "That was good!" or "Try again, that wasn’t quite right." The robot uses those comments to figure out what it should do next.
Why It Matters
This method helps the robot learn more naturally, like how you learn from your mistakes with help from a friend. It’s not just following strict rules; it's learning from real-life feedback, making it smarter and more helpful over time.
