Unfortunately, far too many methods today are called 'AI', but in the end it is just another target for machine learning. But what can you do - this is marketing.

A really wonderful application scenario for the technology has now been developed by Dmitriy Smirnov et.al.:

The generation of sprite sheets from video animations. 🏁

What happens here, is that the ML is trained to separate foreground sprites from background, and to store individual animation phases in a sprite sheet in a meaningful and usable way.

Admittedly PixelArt is an art. Hardly any game designer will let herself be deprived of this fun. But when it comes to getting as much sprite as possible into as small a map as possible, this approach could be quite helpful. 

All information about Marionette is also available on github. You find the docs as well as the full source code and given some patience you will be up and running quite quickly.
