Part 6/13:

A philosophical distinction is made between imitation learning and reinforcement learning:

• Imitation Learning: Tesla's AI models learn by copying high-quality human drivers. This approach provides baseline behaviors, anchoring AI performance to human expertise.

• Reinforcement Learning (RL): Tesla enhances AI beyond imitation by rewarding desirable behaviors and penalizing unsafe or inefficient ones within simulated environments. This allows systems to discover novel solutions, improve decision-making, and evolve capabilities that surpass human benchmarks.

Philbert emphasizes that RL is crucial for tasks like avoiding pedestrians dynamically or optimizing for unpredictable scenarios—areas where rigid human data might be insufficient.
