Huang (Huang Yonghong) is really good at this; last year it was WALL-E, this year it's Olaf to finish things off. A few little-known facts: 1. The dialogue isn't AI; it's pre-recorded to prevent embarrassing moments. 2. Olaf's eyebrows, nose, and arms are all magnetic, specifically for children to pluck and then pretend to be in pain. 3. Using only an RTX 4090 for training, Olaf learned to walk and move in just two days. 4. Heat dissipation also relies on AI learning to mitigate heat.
