Defining the optimal error rate in terms of bias
Question: When conducting bias and variance analysis, what does the optimal error rate represent in terms of the types of error a model can have?
Sample answer: The optimal error rate represents the unavoidable bias or irreducible error that no model can overcome for a given task.
Key points:
- Represents unavoidable bias.
- Constitutes the irreducible error floor for a task.
Rubric: Awards full credit if the student identifies the optimal error rate as unavoidable bias or irreducible error.
