Guiding Development Tactics Through Machine Learning Error Analysis
Question: According to Andrew Ng's Machine Learning Yearning, why is it critical for a practitioner to understand bias and variance before choosing tactics to improve a model?
Sample answer: Understanding bias and variance is critical because it helps a practitioner decide whether tactics to improve performance, such as adding more training data, are a good use of time.
Key points:
- Understanding bias and variance helps evaluate development tactics.
- It helps decide if adding data or other tactics is a good use of time.
Rubric: Must state that understanding bias and variance helps the practitioner decide if adding data or other performance-improving tactics are a good use of time.
