Lesson 1 · How AI Learns
Getting the shown examples right isn't enough.
A student memorises the exact five sums the teacher solved in class — and then freezes when the exam has new numbers.
An untested AI can fool you the same way. That's why we test.
Testing an AI on examples it has never seen answers the real question:
Did it learn the pattern, or just memorise the answers?
Only fresh examples can tell them apart.
