Explain the iterative nature of error analysis.
Question: Based on Ng's explanation in Machine Learning Yearning, explain why error analysis is considered an iterative process. Detail the typical cycle a practitioner goes through when defining error categories for misclassified examples.
Sample answer: Error analysis is iterative because categories are not strictly predefined. A practitioner often starts with no categories, examines a few examples to brainstorm initial categories, and begins manual categorization. During this process, new categories often emerge, requiring the practitioner to revisit and re-examine previously analyzed examples under these new categories.
Key points:
- Categories do not need to be predefined.
- Initial examples inspire the first set of categories.
- Manual categorization often reveals the need for new categories.
- Previous examples must be re-examined when new categories are added.
Rubric: Full credit for mentioning starting without categories, brainstorming after seeing initial examples, discovering new categories during manual categorization, and re-examining examples with new categories.
