Adding Artificial Blur to Training Photos
If development-set traffic-sign photos are blurrier than the training photos, the cleaner training images can be augmented with synthetic motion blur so the two data sets look more alike.

When Synthetic Data Becomes Useful
What does artificial data synthesis help you build when your development set is missing important cases?
True or False: If your validation data contains an important rare pattern, generating synthetic examples can help enlarge the training set so it better covers that pattern.
Artificial data synthesis can help create a _____ that better matches the validation set.
What is the main advantage of synthetic data when your training set does not match the dev set?
Artificially generated examples always match the dev set’s real-world distribution exactly.
Artificially generated examples can help create a _____ dataset that still resembles the development set.
