Shared Label Mapping Across Data Sources
The case for combining internet images with mobile-app images relies on an x-to-y mapping that works well for both types of data. Such a system can input either an internet image or a mobile-app image and reliably predict the label without knowing the image source.

According to Machine Learning Yearning, what is the primary criterion for choosing dev and test sets?
True or False: When building a dev/test set, it is safe to assume the training distribution is the same as the test distribution.
Dev and test sets should contain examples that reflect what you ultimately want to perform well on, rather than only the _____ you happen to have for training.
Why is using a simple 30% random split of available data as your test set problematic when future data differs from training data?
According to ML Yearning, it is generally safe to assume your training data distribution is the same as your test data distribution.
Dev and test sets should be chosen to reflect data you expect to get in the _____ and want to do well on.

According to ML Yearning, what should the examples in your dev and test sets primarily reflect?
According to ML Yearning, dev and test sets must always come from the same distribution as the training data.
ML Yearning warns that the test set should not simply be _____ of the available data when future data differs from the training set.
Match each data scenario to the correct dev/test set strategy decision according to ML Yearning.
