Short Answer

Explain why simulated motion blur is added to clear training images

Question: Why would an engineer add simulated motion blur to clear internet images in a training set for a cat detector?

Sample answer: The engineer adds simulated motion blur to make the training images more similar to the dev set, which naturally contains blurry images from cellphone users moving their phones.

Key points:

  • Make training images more similar to the dev set.
  • Compensate for motion blur in the dev set caused by cellphone users' movement.

Rubric: The answer must state that it makes the training set more similar to the dev set to address the distribution difference caused by blurry cellphone images.
