The Error That Cannot Be Reduced Further
Question: In model evaluation, what term is used for the part of error that remains even for the best possible predictor when the minimum achievable error is still above zero?
Sample answer: It is called irreducible error, also known as Bayes error.
Key points:
- Irreducible error.
- Bayes error.
Rubric: The answer must include the phrase 'irreducible error' or 'Bayes error.'
