Transcript
Here you see an incredible new robot that learned to explore, stand up, and even handle packages. And more. Now, wait a second. What you see here should be impossible! So, why is that? Why is this impossible? Dear Fellow Scholars, this is Two Minute Papers with Dr. Károly Zsolnai-Fehér. Well, to understand what is going on here, let’s look... Read More
Questions & Answers
Q: Why is it difficult for robots to learn in the real world?
Unlike language models, robotics lacks sufficient training data in the real world, making it challenging for robots to learn.
Q: How does reinforcement learning work in video game simulations?
Reinforcement learning in simulations involves giving rewards to robots based on their performance, encouraging them to explore and understand the virtual world.
Q: What is the "TV problem" faced by AI agents?
The "TV problem" refers to AI agents becoming addicted to new information and being reluctant to leave a specific task or environment, similar to human behavior.
Q: How does engineering the rewards help robots learn specific tasks?
By crafting rewards that incentivize desired behaviors, robots can learn to perform tasks such as opening doors and moving objects based on the reward signals they receive.
Summary & Key Takeaways
-
Large language models can be trained with tons of data, but robots lack sufficient training data in the real world.
-
The solution is to let robots learn inside a simulation, where they can play video games and receive rewards for performing well.
-
By engineering the rewards in the game, robots can learn to navigate, stand up, open doors, and handle packages competently.
