Lesson 5 of 11
Learning the examples instead of the pattern
Show on a big screenShow the program every crate. Can it still be wrong?

Step 1 of 4
- All twenty-four crates become examples.
- Ask about a crate it holds: distance 0. It copies the word.
- Score on its own examples: 24 of 24.
- Score on the next morning's twenty: 14 of 20.
The rule
Yes. It can still be wrong on a crate it has not seen. A crate is held when it is one of the program's examples. Distance 0 means the same marked count and the same kilos.
A nearest-example program that holds a crate finds it at distance 0. So it copies that crate's word. That is automatic, not a skill. The only count that matters covers crates it has never seen.
- A perfect score on its own examples proves nothing new.
| Measured on | Score |
|---|---|
| Its own 24 examples | 24 of 24 |
| The next morning's 20 | 14 of 20 |
The examples hold both full-price and cut-price crates. The program still misses 20 − 14 = 6 of the next twenty.
