Short Answer

What must be true for a system to reliably predict labels from either an internet image or a mobile-app image?

Question: In one to three sentences, explain what must be true of a system for it to reliably predict labels from either an internet image or a mobile-app image.

Sample answer: There must exist a single x-to-y mapping that works well for both types of data, allowing the system to predict the correct label whether the input is an internet image or a mobile-app image, without needing to know which source the image came from.

Key points:

  • A shared x-to-y mapping must work well for both data types
  • The system predicts the label reliably regardless of source
  • The system does not need to know the image's source

Rubric: Full credit for stating that a shared x-to-y mapping must work well for both sources and that the system predicts labels correctly without knowing the image's source.
