Explain the core purpose and proper handling of a Blackbox dev set.
Question: Based on the course material, define what the Blackbox dev set is, identify three specific tasks it can be used for, and explain the key rule regarding how developers must interact with it.
Sample answer: The Blackbox dev set is the second subset of a split dev set that contains the remaining examples after the Eyeball dev set has been drawn. It can be used to automatically evaluate classifiers by measuring their error rates, select among different algorithms, and tune hyperparameters. The key rule for interacting with the Blackbox dev set is that developers must avoid looking at it with their eyes to ensure that evaluations remain strictly unbiased.
Key points:
- The Blackbox dev set consists of the remaining examples in a split dev set after the Eyeball dev set is established.
- It is used to automatically evaluate classifiers, select algorithms, and tune hyperparameters.
- Developers must avoid looking at the Blackbox dev set with their eyes to maintain its utility for blind, automatic evaluations.
Rubric: The response must correctly define the Blackbox dev set as the remaining subset after the Eyeball dev set is drawn. It must list all three primary uses: evaluating classifiers automatically (measuring error rates), selecting among algorithms, and tuning hyperparameters. Finally, it must specify the rule that developers must not manually examine or look at the data.
