IS (Inception Score) measures: diversity and quality of generated images

Can you tell if a painting is good just by looking at it?

Imagine you're at an art gallery, and you see a painting that looks impressive. You wonder if it's truly good or just a random mix of colors.

Think of the painting as a bunch of different colors thrown together. A good painting has a clear theme, like a story or a feeling, making it easy to understand. The Inception Score (IS) checks if the painting (or generated image) is both clear in its theme and varied in its details.

Example

If the painting had a clear theme like "a sunny day at the beach," but all the colors were the same shade of blue, it wouldn't be as good.

Remember this

The IS helps us know if an image is both meaningful and varied, like a good painting.
