AI Has Tiny Numbers Called "Weights"

Inside every AI are billions of tiny numbers called weights. These weights decide how the AI makes decisions.

At the start of training, these weights are random — the AI is basically guessing!

Start: Weights = [0.3, -0.7, 0.1, 0.9, ...] (random!)
Result: AI guesses wrong most of the time 😅

After 100 examples: Slightly better
After 10,000 examples: Getting there!
After 1,000,000 examples: Pretty good!
After 100,000,000 examples: Expert level! 🏆

Training AI is EXACTLY like training a dog:

🤯 AlphaGo: The Ultimate Practice Session

AlphaGo beat the world's best Go player in 2016. How did it practice?

1. First: Learned from 160,000 human games
2. Then: Played itself 30 million times in a few weeks
3. Result: Better than any human who has EVER played

Humans play maybe 10,000 games in a lifetime. AlphaGo played 30 MILLION!

That's the power of AI practice: unlimited games, no breaks, no sleep needed!
