I'd be interested to see if similar techniques could be used for scaling up pixel art. Tools to upscale pixel art do exist already, but the results are a bit hit and miss. Could be a good stress test for the machine learning algorithms too.
That sounds interesting. Do you have any links?
I must not understand what you mean by scaling up, I though the best way to scale up pixel art was to disable interpolation, so each pixel just becomes a perfectly sharp square?

Plenty to take a look at here:
Existing pixel-art-specific upscaling methods are going to be better than this, for pixel art.
But if they wanted they could probably try to train their neural network for pixel art specifically, similar to https://github.com/nagadomi/waifu2x
