What is the test set's role, and what two decisions must it not guide?
Question: Answer in one to three sentences.
Sample answer: The test set is used to evaluate algorithm performance. It must not guide the choice of learning algorithm or the choice of parameters.
Key points:
- Evaluate algorithm performance.
- Do not select the learning algorithm.
- Do not select parameters.
Rubric: The answer should name performance evaluation and exclude both algorithm selection and parameter selection.
