問題文
A team must report how close their image generator is to real photographs. A reviewer asks for the distribution-distance score of one specific generated picture that appeared in a demo. How should the team respond?
選択肢
- Compute the score using that picture as the generated set and the whole real collection as the reference set, and report the number with a note that the sample size on the generated side was one so the reviewer can interpret it with appropriate caution.
- Substitute a perceptual similarity score against the nearest real photograph.
- Explain that the score compares the statistics of a set of generated images with the statistics of a set of real images, so a single picture has no value for it.
- Report the score of the batch the picture came from and present it as the score of that picture.
