That's interesting! One thing I was surprised about is that they don't address optimizing the palette and dither pattern across time (b/c most gifs are animated). This feels to me like it would be really interesting and a hard problem for traditional algorithms. They do mention it as a possibility for future work at the end tho. They also seem to have separate losses for the palette net and the dither net instead of just adjusting both to optimize a general image quality metric (although it does look like they have some kind of perceptual loss, it's just not the only objective)
