A guess can sound sure and still be wrong
Spam is junk email. A spam program learned a rule from six practice messages. The rule counts the "!" marks in a message. Two or more marks means junk. The rule was right on all six.
Step 1 of 4
- The rule: lots of exclamation marks means junk.
- It got all six practice messages right.
- A teacher's real note also has two marks.
- The rule calls it junk. It is wrong.
An AI can sound sure and still be wrong.
An AI learns from examples. With few examples, it can get a new case wrong. The rule was right on all six, so it says "100% sure". It says the same on a new case.
Test three messages. Watch how sure the rule stays.
