Contrast domain adaptation research with application-focused dataset strategies.
Question: Discuss the difference in priorities when tackling domain adaptation as a research problem versus aiming to make progress on a specific machine learning application, according to Machine Learning Yearning.
Sample answer: While developing algorithms that train on one distribution and generalize well to another (domain adaptation) is a valuable research pursuit, it is less efficient for practical applications. For a specific application, ML Yearning recommends choosing dev and test sets from the same distribution because domain adaptation methods are usually only applicable in special problem types.
Key points:
- Domain adaptation aims to train an algorithm on one distribution to generalize to another.
- It is an important research problem but typically applicable only to special problem types.
- For practical application progress, teams should choose dev and test sets from the same distribution.
- This same-distribution strategy increases team efficiency compared to attempting domain adaptation.
Rubric: The response should contrast the broad goals of research on domain adaptation with the efficiency-focused strategy of using same-distribution dev and test sets for specific applications.
