Contrast of Classifier Refinement Decisions
Question: How does the presence of a dev set and metric change a machine learning team's decision-making process when deciding which classifier ideas to keep refining?
Sample answer: A dev set and metric allow the team to quickly detect whether new classifier ideas yield small or large performance improvements. This rapid feedback enables them to quickly decide which ideas to keep refining and which ones to discard, avoiding the slow process of manual app testing.
Key points:
- Allows quick detection of small or large improvements.
- Enables fast decisions to keep refining successful ideas and discard unsuccessful ones.
Rubric: The answer should state that a dev set and metric allow quick detection of small or large improvements, enabling fast decisions on which ideas to keep refining versus which to discard.

What does having both a dev set and metric enable a team to do that manual app testing does not?
According to Ng, manually testing each new classifier by playing with the app is a fast, efficient evaluation method.
Without a dev set and metric, each time a team develops a new classifier, they must _____ it into the app to evaluate it.
Match each concept to its role in the classifier evaluation process described by Ng.
